The SSH init script only kills the main daemon which leads to any child
processes (for remaining connections) being untouched.
killproc returns 4 (unknown error) when not all processes were killed
which is not intended here. Therefore we ignore the error and do not
pause the shut down process for a minute.
Fixes: #12544

The SSH daemon was not terminated properly because killproc
tried to terminate all processes with that name. That caused
that the master daemon respawned some processed which were
therefore not killed because killproc determined a list of
PIDs only once before starting sending signals.
This patch only kills the master process which is being
determined by using sshd's pid file.
That results in all established connections not being
interrupted any more.
Furthermore, the loadproc function checks if any processes
with the given name are already running which could be true
if there are any connections still open.
That check is being disabled with the -f switch and sshd
will always be launched.
"/etc/init.d/sshd stop" might now print FAIL if only the
master process, but no connection processes were terminated.
