[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. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
