Exception in xen/util/vscsi_util.py while starting xend
 
We have pscsi device with long scsi ids like 15:0:11:101.
In this case lsscsi prints no "blank" between id and type,
so the following split of the string returns wrong output.
The field physical_HCTL is set to 15:0:11:101]dis.
The patch replaces char "]" by "] ", so split() will return the right
physical_HTCL.
