md: support re-add of recovering devices.
We currently only allow a device to be re-added if it appear to be in-sync. This is overly restrictive as it may be desirable to re-add a device that is in the middle of recovery. So remove the test for "InSync" - the test on rdev->raid_disk is sufficient to ensure that the re-add will succeed.
