    Pass the sense reason as an explicit return value from the I/O submission
    path instead of storing it in struct se_cmd and using negative return
    values.  This cleans up a lot of the code pathes, and with the sparse
    annotations for the new sense_reason_t type allows for much better
    error checking.
    
    (nab: Convert spc_emulate_modesense + spc_emulate_modeselect to use
          sense_reason_t with Roland's MODE SELECT changes)
