Log:
  fusefs: clear fuse_getattr_in.getattr_flags
  
  Protocol 7.9 adds this field.  We could use it to store the file handle of
  the file whose attributes we're requesting.  However, that requires extra
  work at runtime to look up a file handle, and I'm not aware of any file
  systems that care.  So it's easiest just to clear it.
