kernel/user.c: add lock release annotation on free_user()

Browse Source 
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
