Title
RDMA/irdma: Fix a window for use-after-free
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix a window for use-after-free During a destroy CQ an interrupt may cause processing of a CQE after CQ resources are freed by irdma_cq_free_rsrc(). Fix this by moving the call to irdma_cq_free_rsrc() after the irdma_sc_cleanup_ceqes(), which is called under the cq_lock.
