md: adjust resync_min usefully when resync aborts.
When a 'check' or 'repair' finished we should clear resync_min so that a future check/repair will cover the whole array (by default). However if it is interrupted, we should update resync_min to where we got up to, so that when the check/repair continues it just does the remainder of the array.
