quota: move unmount handling into the filesystem
Currently the VFS calls into the quotactl interface for unmounting filesystems. This means filesystems with their own quota handling can't easily distinguish between user-space originating quotaoff and an unount. Instead move the responsibily of the unmount handling into the filesystem to be consistent with all other dquot handling. Note that we do call dquot_disable a lot later now, e.g. after a sync_filesystem. But this is fine as the quota code does all its writes via blockdev's mapping and that is synced even later.
