[SCSI] gdth: !use_sg cleanup and use of scsi accessors
gdth_execute() will issue an internal, none scsi-standard commands
onto __gdth_queuecommand(). Since it is not recommended to set
struct scsi_cmnd IO members in llds, gdth now uses internal IO
members for IO. In the case of gdth_execute() these members will be
set properly. In case the command was issued from scsi-ml
(by gdth_queuecommand) they will be set from scsi IO accessors.
* define gdth IO accessors and use them throughout the driver.
* use an sg-of-one in gdth_execute() and fix gdth_special_cmd()
accordingly.
* Clean the not use_sg code path and company
