dm mpath: validate table argument count
commit 0e0497c0c017664994819f4602dc07fd95896c52 upstream.
The parser reads the argument count as a number but doesn't check that
sufficient arguments are supplied. This command triggers the bug:
dmsetup create mpath --table "0 `blockdev --getsize /dev/mapper/cr0`
multipath 0 0 2 1 round-robin 1000 0 1 1 /dev/mapper/cr0
round-robin 0 1 1 /dev/mapper/cr1 1000"
kernel BUG at drivers/md/dm-mpath.c:530!
