net/mlx4_core: Implement resource quota enforcement
Implements resource quota grant decision when resources are requested,
for the following resources: QPs, CQs, SRQs, MPTs, MTTs, vlans, MACs,
and Counters.
When granting a resource, the quota system increases the allocated-count
for that slave.
When the slave later frees the resource, its allocated-count is reduced.
A spinlock is used to protect the integrity of each resource's free-pool counter.
(One slave may be in the process of being granted a resource while another
slave has crashed, initiating cleanup of that slave's resource quotas).
