stmmac: fix check for phydev being open
commit dfc50fcaad574e5c8c85cbc83eca1426b2413fa4 upstream.
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.
