py/asmx86: Remove unused 5th argument facility.
In commit 71a3d6ec3bd02c5bd13334537e1bd146bb643bad mp_setup_code_state was
changed from a 5-arg function to a 4-arg function, and at that point 5-arg
calls in native code were no longer needed. See also commit
4f9842ad80c235188955fd83317f715033a596c0.
