stm32/usbd_msc: Provide Mode Sense response data in MSC interface.

Browse Source 
Eventually these responses could be filled in by a function to make their
contents dynamic, depending on the attached logical units.  But for now
they are fixed, and this patch fixes the MODE SENSE(6) responses so it is
the correct length with the correct header.
