container-common: remove old check

container-common: remove old check

This removes a bit of unnecessary code, the check was always wrong
because of the condition 'not ceph_current_status.get('rc', 1) == 0'
It will never match since `Not` is used for bool and we are checking for
an rc.
Also, even though the check would work, this will be a major blocker for
a complete meltdown. If the whole platform is shutdown then nothing will
be up but files will be present, so this check is definitely wrong.
