fc-loadtool flash ID check: change of reset after the check logic This change only affects those flash configurations that have ID checks enabled. The logic for resetting the flash after the ID check has been changed as follows: 1) If the check fails, we return without attempting to reset the flash. 2) If the check is successful, we reset the flash using the configured method (could be AMD or Intel or Intel W30) instead of always doing an AMD flash reset as the original code did.
