commit 571428be550fbe37160596995e96ad398873fcbd upstream.
free_user() releases uidhash_lock but was missing annotation. Add it.
This removes following sparse warnings:
include/linux/spinlock.h:339:9: warning: context imbalance in 'free_user' -
unexpected unlock
kernel/user.c:120:6: warning: context imbalance in 'free_uid' - wrong count at
exit
