Title
RDMA/hns: Fix cpu stuck caused by printings during reset
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix cpu stuck caused by printings during reset During reset, cmd to destroy resources such as qp, cq, and mr may fail, and error logs will be printed. When a large number of resources are destroyed, there will be lots of printings, and it may lead to a cpu stuck. Delete some unnecessary printings and replace other printing functions in these paths with the ratelimited version.
