staging: rtl8188eu: core: Replace memcpy() with ether_addr_copy() if ethernet addresses are __aligned(2)

This patch fixes the checkpatch warning:
Prefer ether_addr_copy() over memcpy() if the Ethernet addresses are
__aligned(2)
Done using coccinelle:

@@
expression exp1, exp2;
@@
- memcpy(exp1, exp2, ETH_ALEN);
+ ether_addr_copy(exp1, exp2);

The output of pahole shows that the addresses are aligned:
