[ upstream commit e6cbfd9bf30bbc4170fe8c7c04a16d9cf795fb90 ]

Previously used 'random_ether_addr()' API is removed in upstream kernel
with commit
Commit ba530fea8ca1 ("ethernet: remove random_ether_addr()")

Replacement API 'eth_random_addr()' is around since v3.6 [1], so
simply switching to this API without any version checks.

0a4dd594982a ("etherdevice: Rename random_ether_addr to eth_random_addr")
