fold lock_for_kill() and __dentry_kill() into common helper

Browse source

There are two callers of lock_for_kill() and both are followed
by the same sequence of actions:
	* in case of failure, drop ->d_lock, do rcu_read_unlock() and
go away
	* in case of success, do rcu_read_unlock() followed by
passing dentry to __dentry_kill(); if the latter returns NULL, go away.

All calls of __dentry_kill() are paired with lock_for_kill() now;
let's turn that sequence into a new helper (dentry_kill()) and switch
to using it.
