RDMA/hns: Support userspace configuring congestion control algorithm with QP granularity

Browse source 
Currently, congestion control algorithm is statically configured in
FW, and all QPs use the same algorithm(except UD which has a fixed
configuration of DCQCN). This is not flexible enough.

Support userspace configuring congestion control algorithm with QP
granularity while creating QPs. If the algorithm is not specified in
userspace, use the default one.
