openssh: fix sshd status command error prompt

sshd status command results in error prompt:

root@qemu0:~# /etc/init.d/sshd status
/usr/sbin/sshd (pid 1199) is running...
/etc/init.d/sshd: line 100: return: can only `return' from a
function or sourced script

"service --status-all" command also display wrong status for sshd.

This commit fix this error prompt and make service command display
right status for sshd.
