Merge fifo_vnops.c:1.117 from HEAD to RELENG_6:

Browse Source 
After going to some trouble to identify only the write-related events
  to poll the write socket for, the fifo polling code proceeded to poll
  for the complete set of events.  Use 'levents' instead of 'events' as
  the argument to poll, and only poll the write socket if there is
  interest in write events.
