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.
