FAFT: Ignore the failure of getting boot id and move its call location

On some device, it failed to read the boot id file. Ignore this failure
tempoarily in order not to block the test. And also move its call location
to before the userspace_action as some userspace_action does reboot.

BUG=chrome-os-partner:19185
TEST=run firmware_ConsecutiveBoot passed.
