ovs-lib: Return the correct exit status of the command 'status'

commit 46528f78e5c(debian, rhel, xenserver: Ability to collect ovs-ctl logs)
made changes in the startup scripts such that the o/p of ovs-ctl is logged
into ovs-ctl.log. But it had an unintended consequence that the exit status
of ovs-ctl was no longer returned. We would always return success(the exit
status of tee).

With this commit, we return the exit status of ovs-ctl instead of tee.
