[PATCH 1/3] Allow SCSI hosts to be less verbose

[Matthew Wilcox <matthew-Ztpu424NOJ8@public.gmane.org>]

From: Matthew Wilcox <willy-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>

Introduce a 'quiet' flag in the scsi_host_template which drivers can
set to prevent (in the first instance) printing their name when they
register with the SCSI core.  Set the quiet flag in the USB Storage
driver.
