[PATCH] ftgmac100: use bus name in mdio error messages

[Zev Weiss]

Previously we'd been using a device name retrieved via
ftgmac100_data->phydev, but the mdio read/write functions may be
called before that member is initialized in ftgmac100_phy_init(),
leading to a NULL pointer dereference while printing the error message
issued if the mdio access fails.  We can instead use bus->name, which
is already available at that point.
