i40e: use configured RSS key and lookup table in i40e_vsi_config_rss
A previous refactor added support to store user configuration for VSIs, so that extra VSIs such as for VMDq can use this information when configuring. Unfortunately the i40e_vsi_config_rss function was missed in this refactor, and the values were being ignored. Fix this by checking for the fields and using those instead of always using the default values.
