eventpoll: Don't re-zero eventpoll fields

Remove redundant and unnecessary code.

ep_alloc uses kzalloc to create struct eventpoll, so there is no need to
set fields to defaults of 0. This was accidentally introduced in commit
85455c795c07 ("eventpoll: support busy poll per epoll instance") and
expanded on in follow-up commits.
