msg/async/ProtocolV2: send_keepalive under the scope of lock

Dropping lock is dangerous and could be race-prone.
Any time the lock is dropped we need to reverify the connection state.

send_keepalive under the scope of lock should be just fine since
it does not introduce any extra lock dependencies.
