To avoid leaking a running timer we need to wait for the
posted reconfigs after netdev is unregistered. In common
case the process of deinitializing the device will perform
synchronous reconfigs which wait for posted requests, but
especially with VXLAN ports being actively added and removed
there can be a race condition leaving a timer running after
adapter structure is freed leading to a crash.
Add an explicit flush after deregistering and for a good
measure a warning to check if timer is running just before
structures are freed.
