[PATCH v2 3/4] net/i40e: remove redundant vector Rx queue setup code

Tue Sep 2 12:48:58 CEST 2025
Some assignments were being done twice:
1. Marking each rxq as a vector queue
2. Marking the device as vector allowed
This commit makes sure that these are only performed once.
Fixes: 052ae311091c ("net/i40e: use the common Rx path selection infrastructure")
