Vadim Bendebury 56310c97bf usb_updater: improve debugability
When usb update errors happen it helps a lot to be able to see the
actual error code returned by the target and where the error was
generated.

This patch adds a few printouts to help with debugging.

BRANCH=none
BUG=none
TEST=observed proper error messages generated while debugging
     introduction of extension/vendor commands transfer over USB.
