Change-Id: I1c4240ebe5783ca923c310061e2a76947aa6601b

R=reinauer@chromium.org
BUG=chromium-os:14030
TEST=manual

On a Mario:
  crossystem fwupdate_tries=3
  crossystem fwupdate_tries # should be 3
  cat /mnt/stateful_partition/.need_firmware_update # should be 3

  crossystem fwupdate_tries=0
  crossystem fwupdate_tries # should be 0
  cat /mnt/stateful_partition/.need_firmware_update # should complain file doesn't exist

On a newer platform:
  crossystem fwupdate_tries=3
  crossystem fwupdate_tries # should be 3
  cat /mnt/stateful_partition/.need_firmware_update # should complain file doesn't exist

  crossystem fwupdate_tries=0
  crossystem fwupdate_tries # should be 0
  cat /mnt/stateful_partition/.need_firmware_update # should complain file doesn't exist
