Log Message:
-----------
RealtimeIncomingAudioSourceCocoa::OnData rescales the frame counter against
the already-updated sample rate, making it a no-op

Reviewed by Youenn Fablet.
m_sampleRate was overwritten with the new sampleRate before it was
used as the divisor in the frame-count rebase, so the computation
became m_numberOfFrames * r / r — always equal to the original value
instead of rescaling the fallback frame counter across a sample-rate
change. This only affects the timestamp computed when no audio
module is attached yet.
Capture the previous sample rate before overwriting m_sampleRate and
use it as the divisor.
