usb-storage: Correct adjust_quirks to include latest flags 

Commits ae38c78a03
and 00914025cc added quirk flags
US_FL_NO_READ_DISC_INFO and US_FL_NO_READ_CAPACITY_16 to
the usb-storage driver. However they did not add the corresponding flags
to adjust_quirks() in usb.c, so there was no facility for a user
to over-ride/add them via the quirks module parameter.
