proc: less LOCK operations during lookup
Pseudo-code for lookup effectively is:
LOCK kernel
LOCK proc_subdir_lock
find PDE
UNLOCK proc_subdir_lock
get inode
LOCK proc_subdir_lock
goto unlock
UNLOCK proc_subdir_lock
UNLOCK kernel
We can get rid of LOCK/UNLOCK pair after getting inode simply by jumping
to unlock_kernel() directly.
