Description
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.
