Three USB memory sticks will generate two errors when inserted
[...] No Caching mode page present
[...] Assuming drive cache: write through
These errors are generated by the SCSI stack (and printed thrice). The
first error can be avoided by adding the NO_WP_DETECT quirk for these
devices: it will set the skip_ms_page_3f flag which will make the SCSI
code skip MODE SENSE with page=0x3f (and assume these devices are write
enabled).
(The second error can be avoided by downgrading it to a notice, which is
done in a separate commit.)
