net/bonding: fix RSS key config with extended key length

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.
