Mike Christie 8ed657604b vhost-scsi: Fix log flooding with target does not exist errors 
[ Upstream commit 69cd720a8a ]

As part of the normal initiator side scanning the guest's scsi layer
will loop over all possible targets and send an inquiry. Since the
max number of targets for virtio-scsi is 256, this can result in 255
error messages about targets not existing if you only have a single
target. When there's more than 1 vhost-scsi device each with a single
target, then you get N * 255 log messages.

It looks like the log message was added by accident in:

commit 3f8ca2e115 ("vhost/scsi: Extract common handling code from
control queue handler")

when we added common helpers. Then in:

commit 09d7583294 ("vhost/scsi: Use common handling code in request
queue handler")

we converted the scsi command processing path to use the new
helpers so we started to see the extra log messages during scanning.

The patches were just making some code common but added the vq_err
call and I'm guessing the patch author forgot to enable the vq_err
call (vq_err is implemented by pr_debug which defaults to off). So
this patch removes the call since it's expected to hit this path
during device discovery.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
