This patch set will remove the flow rules cache and move to the 
non-cached mode for DV mode. For Verbs mode flow rules, the behavior
will remain the same.
In the device closing stage, all the software resources for flows
created will be freed and corresponding hardware resources will be
released. Then the total cost of the memory will be reduced and the
behavior of mlx5 PMD will comply fully with the ethdev API
After closing a device, all the flow rules stored in application
layer will no longer be valid anymore. Application should synchronize
the database and do not try to destory any rule on this device.
And after a device restarting, all the needed flow rules should be
reinserted via the create routine in the rte_flow lib.
