audiopolicy: clean delayMs to 0 before reevaluate all outputs routing when call state changes

since the delayMs is for updateCallRouting(),
we need to clean delayMs to 0 before reevaluate
all outputs routing when call state changes.
Otherwise, setPhoneState will cost too much time
which will block UI making phone call.
Test: self-test making phone call and check for delay time
Bug: 79187322

Test: delayed time is reduced.
