md: don't reset curr_resync_completed after an interrupted resync
If a resync/recovery/check/repair is interrupted for some reason, it can be useful to know exactly where it got up to. So in that case, do not clear curr_resync_completed. Initialise it when starting a resync/recovery/... instead. Signed-off-by: NeilBrown <neilb@suse.de>
