Subject: [net-next 16/16] net/mlx5e: Fix RQ creation flow for queues which doesn't support XDP

From: Aya Levin <ayal@...dia.com>

Allow to create an RQ which is not registered as an XDP RQ. For example:
the trap-RQ doesn't register as an XDP RQ.

Fixes: 869c5f926247 ("net/mlx5e: Generalize open RQ")
