[PATCH] Remove 'unhandled error code' messages

[Hannes Reinecke <hare@suse.de>]

scsi_io_completion() tries to take some action based on
the command result and sense code. It also displays
'unhandled error code' or 'unhandled sense code' in case
no special handling was found.
This serves as an additional source of confusion to
the unsuspecting user, as the message in fact means
'everything okay, no special casing required',
and not 'oh gosh, something has happened and the system
couldn't deal with it'.

Plus it doesn't add any value for debugging, as the
actual error and sense code is printed with the next
statement anyway.

So remove these lines.
