md: add new helpers to suspend/resume and lock/unlock array
The new helpers suspend the array first and then lock the array,
Prepare to refactor from:
mddev_lock/lock_nointr
mddev_suspend
...
mddev_resuem
mddev_lock
With:
mddev_suspend_and_lock/lock_nointr
...
mddev_unlock_and_resume
After all the use cases is refactored, mddev_suspend/resume() will be
removed.
And mddev_suspend_and_lock() will also replace mddev_lock() for the case
that the array will be reconfigured, in order to synchronize with io to
prevent problems in many corner cases.
