dm flakey: fix a crash with invalid table line
commit 98dba02d9a93eec11bffbb93c7c51624290702d2 upstream.
This command will crash with NULL pointer dereference:
dmsetup create flakey --table \
"0 `blockdev --getsize /dev/ram0` flakey /dev/ram0 0 0 1 2 corrupt_bio_byte 512"
Fix the crash by checking if arg_name is non-NULL before comparing it.
