[PATCH] ide-tape: remove obsolete onstream support

From: Willem Riede <wrlk@riede.org>


The onstream drives, be they scsi, atapi, ieee1394 or usb, are supported by the
osst driver.  When the drives were new, code was introduced in ide-tape
independently, but never really maintained since.  There are issues with the
drives I found and dealt with in osst, that ide-tape doesn't address.

So this code in ide-tape is both redundant and imperfect.  I assumed from
http://marc.theaimsgroup.com/?l=linux-kernel&m=107550547613846&w=2 that there
was buy in for removing it.

When this patch is applied, ide-tape will refuse to attach to an onstream DI
drive, and will write to syslog to use ide-scsi + osst instead.
