  --> https://bugzilla.kernel.org/attachment.cgi?id=279855&action=edit
4.19 patch v2

Better version of the previous patch. They both solve the issue, but the latter
version seems safer since it doesn't rely on whatever state that SCSI happens
to maintain. If we fail direct dispatch, don't ever touch the request before
dispatch.
