BUG/MINOR: select: fix excess number of dead/skip reported

In 1.8, commit ab62f5195 ("MINOR: polling: Use fd_update_events to update
events seen for a fd") updated the pollers to rely on fd_update_events(),
but the modification delayed the test of presence of the FD in the report,
resulting in owner/thread_mask and possibly event updates being performed
for each FD appearing in a block of 32 FDs around an active one. This
caused the request rate to be ~3 times lower with select() than poll()
under 6 threads.

This can be backported as far as 1.8.
