Log:
  msdosfs: mark unused compat-mount fields
  
  The magic number MSDOSFS_ARGSMAGIC, which used to distinguish
  "old" vs "new" msdosfs mount arguments, has not been used since
  2005; it should just go away now.
  
  Likewise, the local-to-Unicode table that changed at the same
  time is unused.
  
  Leave the space reserved in the old style mount arguments, though,
  since we still support the old mount call (via the cmount entry
  point).
