scsi: scsi_debug: Fix missing error code in scsi_debug_init()
Smatch reports: drivers/scsi/scsi_debug.c:6996
scsi_debug_init() warn: missing error code 'ret'
Although it is unlikely that KMEM_CACHE might fail, but if it does then ret
might be zero. So to fix this explicitly mark ret as "-ENOMEM" and then
goto driver_unreg.
