nvme-fc: Prevent null pointer dereference in nvme_fc_io_getuuid()
[ Upstream commit 8ae5b3a6 ] The nvme_fc_fcp_op structure describing an AEN operation is initialized with a null request structure pointer. An FC LLDD may make a call to nvme_fc_io_getuuid passing a pointer to an nvmefc_fcp_req for an AEN operation. Add validation of the request structure pointer before dereference.
