[FFmpeg-devel] [PATCH] Do not set non_interleaved for DV-in-AVI.

It does not make sense (DV is interleaved by design) and
it avoids a crash when the non-interleaved code tries to
use the priv_data of streams created by the DV demuxer.
The crash could be avoided differently, but then that stream
would still lack an index and would not play correctly in
non-interleaved mode.
