md: Use ->curr_resync as last completed request when cleanly aborting resync.
If a resync is aborted cleanly, ->curr_resync is a reliable record of where we got up to. If there was an error it is less reliable but we always know that ->curr_resync_completed is safe. So add a flag MD_RECOVERY_ERROR to differentiate between these cases and set recovery_cp accordingly. Signed-off-by: Jianpeng Ma <majianpeng@gmail.com> Signed-off-by: NeilBrown <neilb@suse.de>
