Remove 44.1 kHz workaround from the iOS AudioDevice.

Browse Source 
Long, long ago, webrtc didn't support audio at 44.1 kHz. As a result we
treated 44.1 kHz audio as 44 kHz. We now have an arbitrary rate
resampler and have no trouble supporting 44.1 (see 1395 for all the
details). I must have missed updating iOS at the time.

This shouldn't result in a visible change as 16 kHz is selected as the
preferred hardware rate.
