TAKE - Be more careful about quota state changes on ro-devices

[Eric Sandeen <sandeen@xxxxxxx>]

Be more careful about quota state changes on ro-devices
We can't allow quota state changes on a read-only device,
this would kick of a failing transaction & shut down the fs.
Previously the test was quota/no quota but we need to disallow
any change wrt user and/or group quota state.
