stmmac: fix check for phydev being open

Current check of phydev with IS_ERR(phydev) may make not much sense
because of_phy_connect() returns NULL on failure instead of error value.

Still for checking result of phy_connect() IS_ERR() makes perfect sense.

So let's use combined check IS_ERR_OR_NULL() that covers both cases.
