Adrian Vovk 9a077230a4 homed: Ensure closed FD is handled before bus req 
Before this fix, the following sequence of events was possible:
1. A client holding a Ref() FD closes their FD
2. kernel sends notification that all clients closed their FDs
3. Another client obtains its own Ref() FD from homed
4. homed handles the notification that all clients have closed their
   Ref() FDs. Thus it loses track of the fact that the session is
   actually still being held open by the client from step 3

This change makes sure that homed won't respond to bus messages (and
thus won't open more Ref() FDs) until it has handled all notifications
about the existing FDs being closed.

logind has had a very similar fix applied to it in
e11544a830
