staging: vt6656: fix Prefer ether_addr_copy() over memcpy() if the Ethernet addresses are __aligned(2)
This patch fixes the following checkpatch.pl warning:
fix Prefer ether_addr_copy() over memcpy()
if the Ethernet addresses are __aligned(2)
Pahole showed that the 2 structs are aligned to u16

u8 id; /* 0 1 */
