net/mlx5: increase number of strides

If WQE ID is used in CQE for Multi-Packet RQ, the ratio of CQE compression
drops a little bit.  In order to reach to 100Gbps with 64B traffic, it is
needed to further save PCIe bandwidth by increasing the number of strides
in a WQE. It is now 64 by default but adjustable by a PMD parameter -
mprq_log_stride_num.
