scsi: inline sg_io_sense_from_errno() into the callers.

Browse source 
Currently sg_io_sense_from_errno() converts the two input parameters
'errno' and 'io_hdr' into sense code and SCSI status. Having
split the function off into scsi_sense_from_errno() and
scsi_sense_from_host_status(), both of which are available generically,
we now inline the logic in the callers so that scsi-disk and
scsi-generic will be able to pass host_status to the HBA.

[Put together from "scsi-disk: Add sg_io callback to evaluate status"
 and what remains of "scsi: split sg_io_sense_from_errno() in two functions",
 with many other fixes. - Paolo]
