phy: mdiobus_register(): initialize all phy_map entries
make sure phy_map entries whose PHY address is masked are initialized to NULL, given that other code (such as mdiobus_unregister for instance) assumes that non-NULL phy_map entries are allocated phy_devices Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org> Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
