xen_disk: cope with missing xenstore "params" node
When disk is a cdrom and the drive is empty the "params" node in
xenstore might be missing completely: cope with it instead of
segfaulting.
Updated in v2:
- actually removed the strchr(blkdev->params, ':') that caused the
segfault;
- free all the allocated strings from xenstore before returning;
Updated in v3:
- set blkdev fields to NULL after free'ing them.
