staging: rtl8192u: replace memset(x,0,ETH_ALEN) by eth_zero_addr(x)

Author: Aya Mahfouz <mahfouz.saif.elyazal@gmail.com>

eth_zero_addr() is a wrapper function for memset if 0 is going to
be assigned to a mac address. The replacement was done by the
following coccinelle script:

-memset(e,\(0xff\|0xFF\|255\),ETH_ALEN);
+eth_broadcast_addr(e);
