drbd: queue bitmap writeout more intelligently
The "lazy writeout" of cleared bitmap pages happens during resync, and
should happen again once the resync finishes cleanly, or is aborted.
If resync finished cleanly, or was aborted because of peer disk
failure, we trigger the writeout from worker context in the after
state change work.
If resync was aborted because of connection failure, we should not
immediately trigger bitmap writeout, but rather postpone the
writeout to after the connection cleanup happened. We now do it
in the receiver context from drbd_disconnect().
If resync was aborted because of local disk failure, well, there
is nothing to write to anymore.
