[PATCH] nvme: quiet user passthrough command errors

[Keith Busch <kbusch@meta.com>]

From: Keith Busch <kbusch@kernel.org>

The driver is spamming the kernel logs for entirely harmless errors from
user space submitting unsupported commmands. Just silence the errors.
The application has direct access to command status, so there's no need
to log these.
