[PATCH 1/5] Staging: rtl8192e: Replace memcpy with ether_addr_copy

[Darshana Padmadas <darshanapadmadas@gmail.com>]

This patch fixes the following warning found by checkpatch.pl:
Prefer ether_addr_copy() over memcpy() if the Ethernet addresses are __aligned(2

Pahole showed that the structure for BAReq and Delba is aligned:
struct rtllib_hdr_3addr {
	__le16                     frame_ctl;            /*     0     2 */
	__le16                     duration_id;          /*     2     2 */
	u8                         addr1[6];             /*     4     6 */
	u8                         addr2[6];             /*    10     6 */
	u8                         addr3[6];             /*    16     6 */
	__le16                     seq_ctl;              /*    22     2 */
	u8                         payload[0];           /*    24     0 */

	/* size: 24, cachelines: 1, members: 7 */
	/* last cacheline: 24 bytes */
};
