dm raid: fix false -EBUSY when handling check/repair message
Sending a check/repair message infrequently leads to -EBUSY instead of properly identifying an active resync. This occurs because raid_message() is testing recovery bits in a racy way. Fix by calling decipher_sync_action() from raid_message() to properly identify the idle state of the RAID device.
