If the 'register_netdev()' call fails, we must undo a previous
'bcmgenet_mii_init()' call.
Fixes: 1c1008c793fa ("net: bcmgenet: add main driver file")
Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

The missing 'bcmgenet_mii_exit()' call is added here, instead of in the
error handling path in order to avoid some goto spaghetti code.
