net/mlx5: Decrease default mr cache size
Delete initialization of high order entries in mr cache to decrease initial memory footprint. When required, the administrator can populate the entries with memory keys via the /sys interface. This approach is very helpful to significantly reduce the per HW function memory footprint in virtualization environments such as SRIOV.
