[SCSI] gdth: clean up host private data
- Based on same patch from Christoph Hellwig <hch@lst.de>
- Get rid of all the indirection in the Scsi_Host private data and always
put the gdth_ha_str directly into it.
- Change all internal functions prototype to recieve an "gdth_ha_str *ha"
pointer directlly and kill all that redundent access to the "gdth_ctr_tab[]"
controller-table.
