James Smart f8adfb1d37 scsi: lpfc: Fix illegal memory access on Abort IOCBs ... [ Upstream commit e1364711359f3ced054bda9920477c8bf93b74c5 ] In devloss timer handler and in backend calls to terminate remote port I/O, there is logic to walk through all active IOCBs and validate them to potentially trigger an abort request. This logic is causing illegal memory accesses which leads to a crash. Abort IOCBs, which may be on the list, do not have an associated lpfc_io_buf struct. The driver is trying to map an lpfc_io_buf struct on the IOCB and which results in a bogus address thus the issue. Fix by skipping over ABORT IOCBs (CLOSE IOCBs are ABORTS that don't send ABTS) in the IOCB scan logic.
