ssh: Ignore any errors when stopping daemon

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
