Bug 1162840

+++ This bug was initially created as a clone of Bug #1149829 +++

Description of problem:
When you have a suborg using a channel shared by trust from the parent org, you're not able to use the channel.software.listSubscribedSystems api method.

Version-Release number of selected component (if applicable):
spacewalk-java-2.0.2-85.el6sat.noarch

How reproducible:
100%

Steps to Reproduce:
1. In the parent org, create a sub org
2. In the parent org, create a trust to the sub org
3. In the sub org, register a system and give it the channel shared by trust from the parent
4. Use the api script to try to list it:
$ perl 00920875.pl 
channel id: 101 and label: rhel-x86_64-server-5
channel id: 102 and label: rhel-x86_64-server-6
channel id: 112 and label: rhel-i386-server-5.5
channel id: 109 and label: rhel-i386-as-4
channel id: 110 and label: clone-rhel-x86_64-server-6
channel id: 111 and label: mycustomchan
channel id: 113 and label: parentorgchannel
Fault returned from XML RPC Server, fault code -210: redstone.xmlrpc.XmlRpcFault: No such channel: parentorgchannel
$ cat 00920875.pl
#!/usr/bin/perl
use Frontier::Client;

my $HOST = 'spacewalk.example.com';
my $user = 'suborgadmin';
my $pass = 'redhat';
my $chanlabel = 'parentorgchannel';

my $client = new Frontier::Client(url => "http://$HOST/rpc/api");#, debug=>1);
my $session = $client->call('auth.login',$user, $pass);

my $channels = $client->call('channel.listAllChannels', $session);

# dereference (@) the perl array to loop
for (@{$channels}) {
      print "channel id: " . $_->{'id'};
      print " and label: " . $_->{'label'} . "\n";
}


my $systems = $client->call('channel.software.listSubscribedSystems', $session, $chanlabel);
 
# dereference (@) the perl array to loop
for (@{$systems}) {
  print "system id: " . $_->{'id'};
  print " and name: " . $_->{'name'} . "\n";
}

$client->call('auth.logout', $session);   

Actual results:
Fault returned from XML RPC Server, fault code -210: redstone.xmlrpc.XmlRpcFault: No such channel: parentorgchannel

Expected results:
To have the system returned like
system id: 1000010002 and name: gss-rhel6u3-64.usersys.redhat.com

This error exactly as described (for listSubscribedSystems) is fixed already in Spacewalk 2.2, however the same problem still exists for 

channel.software.isUserSubscribable
channel.software.isUserManageable
channel.software.setGloballySubscribable
channel.software.addPackages
channel.software.removePackages
channel.software.clone
channel.software.subscribeSystem (deprecated)

Obviously the ones that involve modifying the channel should return an exception if the channel is not owned by the org of the logged in user, but it should make sense and not be a "no such channel" error.
