Subject: [PATCH] epoll: use kmalloc() in ep_alloc()

Use kmalloc() instead of kzalloc() in ep_alloc(). It seems that
no need to zero-initialize struct eventpoll simply because all
of the fields in the struct will be set properly right after.

The struct might contain paddings in it but IMHO it would not
be a problem since it will not be accessed from the outside of
epoll code.
