6lowpan: revert 'reuse eth_mac_addr()'
This reverts the commit cdf49c283e2e105da86ca575ad35b453f5ff24ea which
replaces lowpan '.ndo_set_mac_address' method by ethernet's one.
Accorind to the IEEE 802.15.4 standard, device has 8-byte length address,
so this hook loses the last 2 bytes which may rise a compatibility problems
with other IEEE 802.15.4 standard implementations.
