Remove unused variable next_step.

This variable is a legacy from the old style faft classes, and now causes an
exception when this code is executed. Removing it.

BUG=chromium:389196
TEST=At desk, ran firmware_FAFTSetup successfully, and also ran it while
putting the device in a bad state. Recovery routine worked fine as well.
