quota: remove invalid optimization from quota_sync_all
Checking the "VFS" quota enabled and dirty bits from generic code means this code will never get called for other implementations, e.g. XFS and GFS2. Grabbing the reference on the superblock really isn't much overhead for a global Q_SYNC call, so just drop this optimization.
