Benjamin Segall 7d9792a8ab epoll: ep_autoremove_wake_function should use list_del_init_careful ...

commit 2192bba03d upstream.

autoremove_wake_function uses list_del_init_careful, so should epoll's
more aggressive variant.  It only doesn't because it was copied from an
older wait.c rather than the most recent.
