net: lan966x: Fix assignment of the MAC address
The following two scenarios were failing for lan966x.
1. If the port had the address X and then trying to assign the same
address, then the HW was just removing this address because first it
tries to learn new address and then delete the old one. As they are
the same the HW remove it.
2. If the port eth0 was assigned the same address as one of the other
ports eth1 then when assigning back the address to eth0 then the HW
was deleting the address of eth1.
The case 1. is fixed by checking if the port has already the same
address while case 2. is fixed by checking if the address is used by any
other port.
