Subject: [net-next V2 08/13] net/mlx5e: Generalize RQ activation

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

Support RQ activation for RQs without an ICOSQ in the main flow, like
existing trap-RQ and like PTP-RQ that will be introduced in the coming
patches in the patchset.
With this patch, remove the wrapper in traps to deactivate the trap-RQ.
