md: two small fixes to handling interrupt resync.
1/ If a resync is aborted we should record how far we got (recovery_cp) the last request that we know has completed (->curr_resync_completed) rather than the last request that was submitted (->curr_resync). 2/ When a resync aborts we still want to update the metadata with any changes, so set MD_CHANGE_DEVS even if we 'skip'.
