Subject: [PATCH] core/cgroup: fix return value of unit_cgorup_freezer_action()

We should return 0 only if current freezer state, as reported by the
kernel, is already the desired state. Otherwise, we would dispatch
return dbus message prematurely in bus_unit_method_freezer_generic().

Thanks to Frantisek Sumsal for reporting the issue.
