staging: rtl8187se: using random_ether_addr() to generate random MAC
Using random_ether_addr() to generate a random Ethernet
address (MAC) that is not multicast and has the local
assigned bit set. Not need to duplicating its implementation.
spatch with a semantic match is used to found this problem.
