description:
Silenced complaints about socket leaks on forced termination.

When graceful shutdown was requested, and then nginx was forced to
do fast shutdown, it used to (incorrectly) complain about open sockets
left in connections which weren't yet closed when fast shutdown
was requested.

Fix is to avoid complaining about open sockets when fast shutdown was
requested after graceful one. Abnormal termination, if requested with
the WINCH signal, can still happen though.
