[SCSI] a4000t, zorro7xx, mvme16x, bvme6000,sim710: xxx_device_remove seems buggy
Fix drivers misusing dev_to_shost Some drivers were using dev_to_shost to go from a struct device to the corresponding shost. Unfortunately, dev_to_shost only looks up the tree to find an shost (it's designed to go from a scsi_device or a scsi_target to the parent scsi_host), and these drivers were calling it with the parent of the scsi_host. I've fixed this by saving a pointer to the Scsi_Host in the drvdata, which matches what most scsi drivers do.
