scsi: xen: scsiback: Fix potential memory leak in scsiback_remove()

Browse Source 
commit 901a5f309d upstream.

Memory allocated for struct vscsiblk_info in scsiback_probe() is not
freed in scsiback_remove() leading to potential memory leaks on remove,
as well as in the scsiback_probe() error paths. Fix that by freeing it
in scsiback_remove().
