net/mlx5: Fix rate limit packet pacing naming and struct

[ Upstream commit 37e92a9d4fe38dc3e7308913575983a6a088c8d4 ]

In mlx5_ifc, struct size was not complete, and thus driver was sending
garbage after the last defined field. Fixed it by adding reserved field
to complete the struct size.

In addition, rename all set_rate_limit to set_pp_rate_limit to be
compliant with the Firmware <-> Driver definition.

Fixes: 1466cc5b23d1 ("net/mlx5: Rate limit tables support")
