Description of problem:
$dom->get_block_job_info can not get correct value for type and end

Version-Release number of selected component (if applicable):
perl-Sys-Virt-1.1.1-2.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.cat test.pl
#!/usr/bin/perl
use warnings;
use strict;
use Sys::Virt;
 
my $uri = "qemu:///system";
my $domname = "tck";
my $con = Sys::Virt->new(address => $uri, readonly => 0);
my $dom = $con->get_domain_by_name($domname);
 
my $jobinfo;
my $pathmain = "/var/cache/libvirt-tck/storage-fs/tck/tck-main";

$jobinfo = $dom->get_block_job_info($pathmain, 0);
while(my ($k, $v) = each %{$jobinfo}) {
    print "$k => $v\n";
}

2. Start a guest with xml
<domain type="kvm">
   <name>tck</name>
   <memory>65536</memory>
   <currentMemory>65536</currentMemory>
   <os>
     <type>hvm</type>
     <kernel>/var/cache/libvirt-tck/os-x86_64-hvm/vmlinuz</kernel>
     <initrd>/var/cache/libvirt-tck/os-x86_64-hvm/initrd</initrd>
   </os>
   <features>
     <acpi />
     <apic />
   </features>
   <devices>
     <disk type="file">
       <source file="/var/cache/libvirt-tck/os-x86_64-hvm/disk.img" />
       <target dev="vda" />
     </disk>
     <disk type="file">
       <driver name="qemu" type="qcow2" />
       <source file="/var/cache/libvirt-tck/storage-fs/tck/tck-main" />
       <target dev="vdb" />
     </disk>
     <console type="pty" />
   </devices>
</domain>

3. run #perl test.pl

Actual results:
cur => 0
bandwidth => 16302096
type => 18577664
end => 16746808

Expected results:
"type" and "end" should be 0 when no block job, and not sure if bandwidth is right because it is different from rhel6 test result
