scsi: lpfc: Fix kernel oops when unmapping SCSI DMA buffers for an aborted cmd
A kernel oops at dma_unmap_sg_attrs() may occur due to a race between an
aborted SCSI I/O completion and a SCSI error handler issued TUR using
the same repurposed scsi_cmnd structure.
The LPFC_DRIVER_ABORTED cmd_flag is set when inflight I/Os are aborted
via lpfc_sli_abort_taskmgmt(), and this flag is not cleared until after
scsi_done() is called. The inflight I/O test is changed to check SCSI
I/O for either LFPC_IO_ON_TXCMPLQ or LPFC_DRIVER_ABORTED. If either
cmd_flag is set, then the I/O should still be counted.
