raid: restore mirror handling in _raid_in_sync

Function is not having the best name since it does check
no just raid LVs to be in sync.

Restore the mirror percentage checking - although without retries,
since only raid target is currently known to need it - for other
types it would be ATM a bug to get inconsistent result.
