vlib: crash in linux_epoll_input_inline for accessing free file index [VPP-1412]
Under rare scenario, epoll may still post an event to VPP although the file
descriptor is already deleted via epoll_ctl (EPOLL_CTL_DEL) and the file
descriptor is close. VPP tries to access the free file index entry and crash.
The fix is to throw away the events which the file descriptor is already deleted.
