[PATCH rdma-next 1/2] IB/mlx5: Refactor raw packet QP modify function

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Alex Vesker <valex-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Added a struct for modifying raw QP, this will allow modifying
multiple parameters in raw packet QP RQ and can also be used for
SQ in the future.
