Simplify the SMP passthrough code by switching it to the generic bsg-lib helpers that abstract away the details of the request code, and gets drivers out of seeing struct scsi_request. For the libsas host SMP code there is a small behavior difference in that we now always clear the residual len for successful commands, similar to the three other SMP handler implementations. Given that there is no partial command handling in the host SMP handler this should not matter in practice.
