usb_updater2: Read bInterfaceNumber correctly.
This patch makes find_interface use bInterfaceNumber explicitly instead
of the i iterator, which could be different from the discovered
interface number if there is no interface at index 0.
BUG=b:229012657
BRANCH=None
TEST=Run 'usb_updater2 -f' on Vell.
