common/mlx5: fix unsigned/signed mismatch

[ upstream commit eec253d0a57d707306e4ac3128bc21f10bb8bc5f ]

Use unsigned int for 2 loop indexes that are being compared against an
unsigned int struct field to avoid signed/unsigned mismatch warning.

Fixes: 718d166 ("net/mlx5: create advanced RxQ table via DevX")
Fixes: e1da60a ("common/mlx5: add DevX command to modify RQT")
