After mnt_hold_writers() has been called we will always have set MNT_WRITE_HOLD and consequently we always need to pair mnt_hold_writers() with mnt_unhold_writers(). After the recent cleanup in [1] where Al switched from a do-while to a for loop the cleanup currently fails to unset MNT_WRITE_HOLD for the first mount that was changed. Fix this and make sure that the first mount will be cleaned up and add some comments to make it more obvious.
