dm raid: fix stripe adding reshape deadlock When initiating a stripe adding reshape, a deadlock between md_stop_writes() waiting for the sync thread to stop and the running sync thread waiting for inactive stripes occurs (this frequently happens on single-core but rarely on multi-core systems). Fix this deadlock by setting MD_RECOVERY_WAIT to have the main MD resynchronization thread worker (md_do_sync()) bail out when initiating the reshape via constructor arguments.
