nvme-rdma: Avoid double freeing of async event data
[ Upstream commit 9134ae2a2546cb96abddcd4469a79c77ee3a4480 ]
The timeout of identify cmd, which is invoked as part of admin queue
creation, can result in freeing of async event data both in
nvme_rdma_timeout handler and error handling path of
nvme_rdma_configure_admin queue thus causing NULL pointer reference.
Call Trace:
