Subject: [PATCH 1/3] scsi: downgrade "write through" error to notice

For some reason all USB memory sticks I happen to have trigger an
    Assuming drive cache: write through

error when inserted into a USB port. But if one looks at the code
paths that trigger this error one notices that in most cases either:
- write through is explicitly requested (via the usb-storage
  NO_WP_DETECT flag);
- preceded by a previous error; or
- preceded by an ordinary notice.

So it seems this error can be safely downgraded to a notice.
