RSS don't work when bond_ethdev_configure called before
rte_eth_bond_slave_add.
This is because internals->rss_key_len is 0 in bond_ethdev_configure().
If internals->rss_key_len is 0, internals->rss_key can not be set
properly.
e.g.:
doesn't work (examples/bond/main.c):
rte_eth_bond_create()
rte_eth_dev_configure()
rte_eth_bond_slave_add()
rte_eth_dev_start()
works (testpmd):
rte_eth_bond_create()
rte_eth_bond_slave_add()
rte_eth_dev_configure()
rte_eth_dev_start()
Fixing by using 'default_rss_key' when 'internals->rss_key_len' is 0.
