common/mlx5: adjust PRM struct size on Windows

Add reserved size to PRM 'struct mlx5_ifc_fte_match_param_bits' for non
Linux OS.  Windows drivers require this extension since their expected
size should match the actual struct size. Linux drivers do not require
this extension and already use calculations based on the shorter size.
Use a static assert to verify that the PRM fte_match_param struct size
remains correct.
