Fix MAC address access in 3c507, ibmlana, pcnet32 and libertas

Commit f001fde5ea changed
net_device.dev_addr from a 32-byte array to a pointer.

I found 4 ethernet drivers which rely on sizeof(dev_addr), which are now
only copying 4 bytes of the address information on 32bit systems.

Fix them to use ETH_ALEN.
