i2c: testunit: don't erase registers after STOP

Browse Source 
[ Upstream commit c422b6a630240f706063e0ecbb894aa8491b1fa1 ]

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.
