staging: vt6655: card.c: replace memcpy() by ether_addr_copy() using coccinelle

This patch focuses on fixing the following warning generated
by checkpatch.pl for the file rxtx.c :

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);

According to ether_addr_copy() description and functionality,
all Ethernet addresses should align to the u16 datatype.

Here is the output of pahole for the relevant datastructures:

struct pmkid_candidate {
        NDIS_802_11_MAC_ADDRESS    BSSID;                /*     0     6 */

        /* XXX 2 bytes hole, try to pack */

        long unsigned int          Flags;                /*     8     4 */

        /* size: 12, cachelines: 1, members: 2 */
        /* sum members: 10, holes: 1, sum holes: 2 */
        /* last cacheline: 12 bytes */
};
