Commit 27c5fd271d8b ("RDMA/hns: The UD mode can only be configured
with DCQCN") adds a restriction that only DCQCN is supported for
UD QPs, but at the same time introduced other problem mistakenly.
Patch #1 reverts the previous modification and fixes the algorithm
issue for UD by configuring congestion control algorithm with QP
granularity.
Patch #2 adds support for userspace configuring congestion control
algorithm with QP granularity.
v1 -> v2:
* Not only revert but also fix the UD algorithm issue in patch #1.
