Fix MAC address access in 3c507, ibmlana, pcnet32 and libertas
Commit f001fde5eadd915f4858d22ed70d7040f48767cf 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.
