bcm63xx_enet: avoid uninitialized variable warning
gcc-7 and probably earlier versions get confused by this function and print a harmless warning: drivers/net/ethernet/broadcom/bcm63xx_enet.c: In function 'bcm_enet_open': drivers/net/ethernet/broadcom/bcm63xx_enet.c:1130:3: error: 'phydev' may be used uninitialized in this function [-Werror=maybe-uninitialized] This adds an initialization for the 'phydev' variable when it is unused and changes the check to test for that NULL pointer to make it clear that we always pass a valid pointer here.
