nvme: quiet user passthrough command errors

Browse source 
[ Upstream commit d7ac8dca93 ]

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

And since every passthrough command now uses the quiet flag, move the
setting to the common initializer.
