net/bonding: fix MAC address reset

Browse Source 
Currently when resetting bond mac address, we are getting the
persisted mac address from slave info considering primary port
as index. But we need to compare the port id from slave info
with the primary port to get the primary slave index and get
the persisted mac address. Without this fix, persisted mac addr
will be zero and rte_eth_dev_default_mac_addr_set will fail.
