* [dpdk-stable] [PATCH] net/mlx5: fix iterator type in Rx queue management

The mlx5_check_vec_rx_support function in the mlx5_rxtx_vec.c file
passes the RX queues array in the loop. Similarly, the mlx5_mprq_enabled
function in the mlx5_rxq.c file passes the RX queues array in the loop.

In both cases, the iterator of the loop is called i and the variable
representing the array size is called rxqs_n.
The i variable is of UINT16_T type while the rxqs_n variable is of
unsigned int type. The size of the rxqs_n variable is much larger than
the number of iterations allowed by the i type, theoretically there may
be a situation where the value of the rxqs_n will be greater than can be
represented by 16 bits and the loop will never end.

Change the type of i to UINT32_T.
