crimson/monc: fix subscription stall that blocked peering.
...
There is a scenario when the `active_con` is properly
chosen but isn't marked as `ready_to_send`.
If `renew_subs()` is called during the `on_session_opened()`,
the flag will be turned on after the subscriptions are
renewed which cannot happen as it requires the flag to be
already set. In other words: there is a circular data dependency.
The net result is stalling the subscription machinery,
particularly the `OSDMap` subs. This caused a nasty peering
issue at Sepia [1] where PG 2.7 got stuck in the `GetInfo`
state.
