i2c: testunit: don't erase registers after STOP

STOP fallsthrough to WRITE_REQUESTED but this became problematic when clearing the testunit registers was added to the latter. Actually, there is no reason to clear the testunit state after STOP. Doing it when a new WRITE_REQUESTED arrives is enough. So, no need to fallthrough, at all.
