[PATCH] media: venus: allow interlaced video streams

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

Venus driver errors out on the interlaced streams with the 'field isn't
supported' error message, which e.g. prevents decoding of the MPEG2
video streams. Don't error out if the buffer is set to contain
interlaced data.

Tested with the fluster enabled to handle MPEG2 through Gstreamer:

./fluster.py r -d GStreamer-MPEG2_VIDEO-V4L2-Gst1.0 -s -so venus-mpeg2.md -j 1
