USB: storage: Add unusual_dev for HP r707



Add "FIX_CAPACITY" entry for HP Photosmart r707 Camera in "Disk" mode.
Camera will wedge when /lib/udev/vol_id attempts to access the last sector,
EIO gets reported to dmesg, and block device is marked "offline" (it is).
Reproduced vol_id behavior with:
	"dd if=/dev/sda of=/dev/null skip=60800 count=1"
