This reverts commit d054858a9c9e4406099e61fe00c93516f9b4c169 which is
commit d2c945f01d233085fedc9e3cf7ec180eaa2b7a85 upstream.
As reported, a lot of scsi changes were made just to resolve a 2 line
patch, so let's revert them all and then manually fix up the 2 line
fixup so that things are simpler and potential abi changes are not an
issue.
