Description of problem:
Using a SAN that has encoded chars in the LUN serial is not possible, because the char is not parseable.

[root@RHEV01 ~]# vdsClient 0 getDeviceList

>>>

note the 'serial': 'SCORAID_Coraid_EtherDriRHEV0101A_\x81' - the \x81 is an encoded char, which fails the parsing.

Version-Release number of selected component (if applicable):
vdsm22-4.5-63.25.el5_6

How reproducible:
always

Steps to Reproduce:
1.set up storage with a non-ascii char in the serial
2.try to use LUN with rhev
3.
  
Actual results:

[root@RHEV01 ~]# vdsClient 0 getDeviceList
Traceback (most recent call last):

  File "/usr/lib64/python2.4/xmlrpclib.py", line 527, in feed
ExpatError: not well-formed (invalid token): line 73, column 48

Expected results:
drop or convert the non-ascii chars
