scsi: scsi_transport_sas: switch to bsg-lib for SMP passthrough
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.
[mkp: typos and checkpatch fixes]
