[PATCH] staging: vt6656: replace memcpy by ether_addr_copy

[Aya Mahfouz <mahfouz.saif.elyazal@gmail.com>]

This patch fixes the following checkpatch.pl warning:

Prefer ether_addr_copy() over memcpy() if the Ethernet addresses are
__aligned(2)

The changes were applied using the following coccinelle
rule: 
@@ expression e1, e2; @@
- memcpy(e1, e2, ETH_ALEN);
+ ether_addr_copy(e1, e2); 

All variables defined in vnt_mac_set_key start at even offsets
making the variables aligned to the u16 datatype.
