net/mlx5: Decrease default mr cache size



[ Upstream commit e8b26b2135dedc0284490bfeac06dfc4418d0105 ]

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.
