drbd: fix potential imbalance of ap_in_flight
When we receive a barrier ack, we walk the ring list of drbd requests
in the transfer log of the respective epoch, do some housekeeping,
and free those objects.
We tried to keep epochs of mirrored and unmirrored drbd requests
separate, and assert that no local-only requests are present in a
barrier_acked epoch.
It turns out that this has quite a number of corner cases and would
add bloated code without functional benefit.
We now revert the (insufficient) commits
drbd: Fixed an issue with AHEAD -> SYNC_SOURCE transitions
drbd: Ensure that an epoch contains only requests of one kind
and instead fix the processing of barrier acks to cope with
a mix of local-only and mirrored requests.
