non-interleaved avi regression

[Carl Eugen Hoyos]

ffplay plays audio badly for one avi sample here because it fails detecting non-interleaved avi. This is a regression since ef8cc06d
I will upload the sample, it is unfortunately very large.

Every audio underrun is clearly audible, no problems with ffmpeg.

Increasing the probesize makes the warning disappear but does not help with the audio problem.
