genhd: fix leftover might_sleep() in blk_free_devt()
commit 46f341ffcfb5d8530f7d1e60f3be06cce6661b62 upstream.
Commit 2da78092 changed the locking from a mutex to a spinlock,
so we now longer sleep in this context. But there was a leftover
might_sleep() in there, which now triggers since we do the final
free from an RCU callback. Get rid of it.
