net/mlx5e: Add trap entity to ETH driver
Introduce mlx5e_trap which includes a dedicated RQ and NAPI for trapped
packets. Trap-RQ processes packets that were destined to be dropped,
but for debug and visibility sake these packets are trapped and reported
to devlink.
Trap-RQ connects between the HW and the driver and is not a part of a
channel. Open mlx5e_create_rq() and mlx5_core_destroy_rq() as API and
add dedicate RQ handlers which report to devlink of trapped packets.
