st_scsi_kern_execute is a helper function to perform SCSI commands synchronously. It supports data transfer with a liner in-kernel buffer (not scatter gather). st_scsi_kern_execute internally uses scsi_execute(). The majority of st_do_scsi can be replaced with st_scsi_kern_execute. This is a preparation for rewriting st_do_scsi to remove obsolete scsi_execute_async().
