md: Use enum for overloaded magic numbers used by mddev->curr_resync
Comments in the code document special values used for
mddev->curr_resync. Make this clearer by using an enum to label these
values.
The only functional change is a couple places use the wrong comparison
operator that implied 3 is another special value. They are all
fixed to imply that 3 or greater is an active resync.
