Here are couple of fixes for msdosfs:
1. A minor change in the debugging output for msdosfs_vfsops.c
2. An important one for msdosfs_vfsops.c: uids are 32 bits not 16 !
   This fixes the "Invalid argument" (EINVAL) error when trying to
   overwrite an already existing file on a writeable DOS filesystem
   with cp(1) or cat(1).
3. A typo in msdosfs_vfsops.c
