net: bcmgenet: Fix a resource leak in an error handling path in the probe functin

Browse Source 
[ Upstream commit 4375ada01963d1ebf733d60d1bb6e5db401e1ac6 ]

If the 'register_netdev()' call fails, we must undo a previous
'bcmgenet_mii_init()' call.

Fixes: 1c1008c793fa ("net: bcmgenet: add main driver file")
