Title: osd: tolerate sessionless con in fast dispatch path

We can now get a session cleared from a Connection at any time. Change
the assert to an if in ms_fast_dispatch to cope. It's pretty rare, but it
can happen, especially with delay injection. In particular, a racing
thread can call mark_down() on us.
