When debugging e.g. the SCSI timeout handler it is important that
requests that have not yet been started or that already have
completed are also reported through debugfs.
This patch depends on a patch that went upstream recently, namely
commit 14e3062fb185 ("scsi: core: Fix a scsi_show_rq() NULL pointer
dereference").
