igbvf: fix MAC address if none assigned by PF

Browse Source 
If use DPDK PF + DPDK VF on igb NICs, we find the MAC address of VF
port is always 0. Because we forget to give it a value if this MAC
address is not assigned by PF. This patch'll assign a random MAC
address to igb VF port as ixgbe does.
