epoll: lock ep->mtx in ep_free to silence lockdep
Technically we do not need to hold ep->mtx during ep_free since we are certain there are no other users of ep at that point. However, lockdep complains with a "suspicious rcu_dereference_check() usage!" message; so lock the mutex before ep_remove to silence the warning.
