ext3: correct mount option parsing to detect when quota options can be changed

We should not allow user to change quota mount options when quota is just
suspended.  I would make mount options and internal quota state inconsistent.
Also we should not allow user to change quota format when quota is turned on.
On the other hand we can just silently ignore when some option is set to the
value it already has (mount does this on remount).
