epoll: Split out the guts of ctl_add and ctl_del

This way we don't do sock lookups when we know they will fail.
Previously, whenever we recursively called __epoll_ctl_add() on the listen
FD, that sock lookup would always fail.

It's a little hard to see from the diff, but this only moves the actual
ctl_add and ctl_del functionality into separate helpers.
