vboot_api_kernel: Print warning in Ctrl-U when dev_boot_usb is not enabled.

Ctrl-U used to simply beep without messages for why it does not work (due to NV
data dev_boot_usb). Since the system is already in Developer mode, it should be
fine to provide some debug information otherwise we can spent time trying to
figure out why the firmware doesn't work.

BRANCH=all
BUG=chrome-os-partner:14474
TEST=flash image to Link, enter DEV and press Ctrl-U; gets beep and warning messages.
