The value of fv_found is set based on the maintained profile info list in the
PMD.
So we need this parameter to add profile id flow for FDIR in the shared code.

Yes, ice_add_prof_id_flow should be processed after ice_add_prof.
It's ok if we just move the ice_add_prof_id_flow processing into func
ice_flow_set_hw_prof,
and delete the func ice_flow_assoc_hw_prof to reduce the code size.
For RSS, the ice_add_prof_id_flow for adding dest_vsi_handle should always be
processed.
So this function has other RSS logic to add soon.
