From: David Gibson
In tcp_epoll_ctl() we pass an event pointer with EPOLL_CTL_DEL, even though
it will be ignored. It's possible this was a workaround for pre-2.6.9
kernels which required a non-NULL pointer here, but we rely on the kernel
accepting NULL events for EPOLL_CTL_DEL in lots of other places. Use
NULL instead for simplicity and consistency.
