(IB, net)/mlx4: Add resource utilization support
Adding visibility of resource usage of QPs, CQs and counters used by virtual functions. This feature will be used to give the PF administrator more data while debugging VF status. Usage info was added to ALLOC_RES command, to notify the PF if the resource which is being reserved or allocated for the VF will be used by kernel driver or by user verbs. Updated reservation and allocation functions of QP, CQ and counter with additional usage parameter.
