fusefs: clear fuse_getattr_in.getattr_flags

Browse Source 
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.
