net: mdio-mux: be compatible with parent buses which only support C45
After the mii_bus API conversion to a split read() / read_c45(), there
might be MDIO parent buses which only populate the read_c45() and
write_c45() function pointers but not the C22 variants.
We haven't seen these in the wild paired with MDIO multiplexers, but
Andrew points out we should treat the corner case.
