Test: osd-recovery-space.sh extends the wait time for "recovery toofull".
The osd-recovery-space test involves writing objects and expecting to receive
the "toofull" flag.
If we don't wait long enough, we might check the "toofull" flag before all objects
have completed writing, and the "toofull" status hasn't been activated yet.
The change will extend the waiting time and will also incorporate additional
checks for the return code from the status wait.
