staging: vt6655: replace memcpy() by ether_addr_copy() using coccinelle and pack variables

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);

After applying the rule, some referencing operations were
adjusted manually to avoid a gcc compilation warning.

According to ether_addr_copy() description and functionality,
all Ethernet addresses should align to the u16 datatype.
A check was made on the following datastructures:

        - vnt_mic_hdr
        - tagS802_11Header
        - tagSEthernetHeader
        - vnt_rts_g
        - ieee80211_rts
        - vnt_private

To maintain that the array abyCurrentNetAddr in vnt_private is aligned,
it was placed before the boolean bLinkPass in the struct definition.
The definition can be found in device.h. A couple of variables were
packed in holes detected by pahole.

Output of pahole when running it on rxtx.o after the changes:
