dm-ioctl: delete a useless condition

Browse Source 
The condition "remaining <= 0" can never be true. The variable remaining
has type size_t, thus it can't be negative. It can't be zero because we
made sure earlier that "remaining > sizeof(struct dm_target_spec)" and
then we added "sizeof(struct dm_target_spec)" to "outptr" (this means
that we subtraceted "sizeof(struct dm_target_spec)" from "remaining").
