[PATCH] vfs: define new lookup flag for chdir
In the "operation does permission checking" model used by fuse, chdir
permission is not checked, since there's no chdir method.
For this case set a lookup flag, which will be passed to ->permission(), so
fuse can distinguish it from permission checks for other operations.
