bnx2x: Clear fip MAC when fcoe offload support is disabled

Browse Source 
[ Upstream commit bbf666c1af ]

On some customer setups it was observed that shmem contains a non-zero fip
MAC for 57711 which would lead to enabling of SW FCoE.
Add a software workaround to clear the bad fip mac address if no FCoE
connections are supported.
