From: Dapeng Yu <dapengx.yu@intel.com>

The original code causes wrong value to be set into PFQF_HENA
register because unnecessary calling to get translated pctype
value for X722 NIC. The result is RSS cannot work.

So remove the unnecessary translation.

Fixes: ef4c16fd9148 ("net/i40e: refactor RSS flow")
