scsi: Remove drivers/scsi/scsi.h

The following two header files have the same file name: include/scsi/scsi.h
and drivers/scsi/scsi.h. This is confusing. Remove the latter since the
following note was added in drivers/scsi/scsi.h in 2004:

"NOTE: this file only contains compatibility glue for old drivers. All
these wrappers will be removed sooner or later. For new code please use
the interfaces declared in the headers in include/scsi/"
