staging/ozwpan: coding style ether_addr_copy

This fixes the following issues detected by checkpatch.pl:

 WARNING: Prefer ether_addr_copy() over memcpy() if the Ethernet addresses are __aligned(2)
 #220: FILE: drivers/staging/ozwpan/ozcdev.c:220:
 +              memcpy(g_cdev.active_addr, addr, ETH_ALEN);
