md: replace is_md_suspended() with 'mddev->suspended' in md_check_recovery()
Prepare to cleanup pers->prepare_suspend(), which is used to fix a
deadlock in raid456 by returning error for io that is waiting for
reshape to make progress in mddev_suspend().
This change will allow reshape to make progress while waiting for io to
be done in mddev_suspend() in following patches.
