mgr/cephadm: still remove daemons in error state if ok-to-stop fails

The ok-to-stop function works for certain daemons
by checking if there are at least a certain number
(typically 1) daemon(s) that are actually running
and saying it's not ok-to-stop if if that won't
be true after the removals. This case breaks down
when all the daemons are in error state, making
it so cephadm will refuse to remove a set of
daemons that aren't even working because they're
not "ok to stop". Since ok-to-stop works in a
yes or no fashion, something like this where we
want to be willing to remove a certain subset
(or potentially all currently deployed) daemons
it's easier to keep this logic as part of applying
the service
