RDMA/bnxt_re: Refurbish CQ to NQ hash calculation
There are few use cases where CQ create and destroy
is seen before re-creating the CQ, this kind of use
case is disturbing the RR distribution and all the
active CQ getting mapped to only 2 NQ alternatively.
Fixing the CQ to NQ hash calculation by implementing
a quick load sorting mechanism under a mutex.
Using this, if the CQ was allocated and destroyed
before using it, the nq selecting algorithm still
obtains the least loaded CQ. Thus balancing the load
on NQs.
