drbd: Call drbd_md_sync() explicitly after a state change on the connection
Without this, the meta-data gets updates after 5 seconds by the md_sync_timer. Better to do it immeditaly after a state change. If the asender detects a network failure, it may take a bit until the worker processes the according after-conn-state-change work item. The worker might be blocked in sending something, i.e. it takes until it gets into its timeout. That is 6 seconds by default which is longer than the 5 seconds of the md_sync_timer.
