[PATCH] Staging: rtl8192u: use is_broadcast_ether_addr() instead of memcmp()

[Wei Yongjun]

From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>

Using is_broadcast_ether_addr() instead of directly use
memcmp() to determine if the ethernet address is broadcast
address.

spatch with a semantic match is used to found this problem.
