    MFS - Fix mmap issues with files under MFS
    
    * MFS relied on specfs to supply a getpages function.  specfs no longer
      exists and MFS's constructed vnode did not point at devfs.
    
      Instead of synthesizing a vnode access the real devfs vnode associated
      with /dev/mfs%d.
    
    * Remove the MFS vnops for its synthesized vnode.  MFS now uses a devfs
      vnode which uses the devfs vnops.
