dpdk-module: replace random_ether_addr() with eth_random_addr()

Browse Source 
random_ether_addr() is finally removed in kernel commit ba530fea8ca1
("ethernet: remove random_ether_addr()"). Backport commit e6cbfd9bf30b
("kni: update kernel API to set random MAC address") from dpdk repo
to use eth_random_addr() instead.

Subject: [PATCH] kni: update kernel API to set random MAC address
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.
