when creating a bonding device, if the slave device's rss key length
= standard_rss_key length + extended_hash_key length, then bonding
device will be same as slave, in function bond_ethdev_configure(),
the default_rss_key length is 40, it is not matched, so it should
calculate a new key for bonding device if the default key could not
be used.
