[PATCH 07/22] scsi: do not decode sense extras

[Hannes Reinecke <hare@suse.de>]

Currently we're only decoding sense extras for tape devices.
And even there only for fixed format sense formats.
As this is of rather limited use in the general case we should
be stop trying to decode things here and rather dump the entire
sense code.
