[PATCH v3 2/2] platform/chrome: cros_ec_proto: remove unnecessary retries

[Dawid Niedzwiecki]

Remove the retry of the get protocol info command. It is not needed
anymore, because RWSIG continue command is send before start of the
probing. That assures the EC device is ready in RW and there is no
need to try again because FPMCU is not fully booted.
