Commit 1d4639567d97 ("mdio_bus: Fix PTR_ERR applied after initialization
to constant") accidentally changed a check from -ENOTSUPP to -ENOSYS,
causing failures if reset controller support is not enabled.  E.g. on
r7s72100/rskrza1:

    sh-eth e8203000.ethernet: MDIO init failed: -524
    sh-eth: probe of e8203000.ethernet failed with error -524

Seen on r8a7740/armadillo, r7s72100/rskrza1, and r7s9210/rza2mevb.
