autotest: Repair the firmware earlier

Firmware is easy to be corrupted when running FAFT. The current
execution sequence of the repair functions makes the repair job
take 1 hour to recover the corrupted firmware. We should run
the firmware repair function earlier. As the function is only
executed on the dedicated pool:faft-test, this change won't
affect other pools.
