dm mpath: free path selector on invalid args
Free path selector if the arguments are invalid.
This command (note that it is invalid) causes reference leak on module
"dm_round_robin" and prevents the module from being removed.
dmsetup create --table '0 2 multipath 0 0 1 1 round-robin /dev/sdh' mpath0
