[PATCH 5.12 363/700] RDMA/hns: Remove the condition of light load for posting DWQE

From: Yixian Liu <redacted>

[ Upstream commit 591f762b2750c628df9412d1c795b56e83a34b3e ]

Even in the case of heavy load, direct WQE can still be posted. The
hardware will decide whether to drop the DWQE or not. Thus, the limit
needs to be removed.
