patches/videoparsers: h264: Disable passthorugh mode enabling

This is a quick fix for regression introduced by the upstream
commit e8908f5aee in h264 videoparser.

The patch is disabling the passthrough mode, otherwise it will
break multi-layer mvc stream parsing.

+Subject: [PATCH] videoparsers: h264: Disable passthorugh mode enabling
+
+Enabling passthorugh mode for optimization is cauing multiple
+issues while parsing MVC streams. Specifically if streams have
+two separate layers (base-view and non-base-view).
+
+Proper fixes needed in many places:
+(handle prefix nal unit, handle non-base-view slice nal extension,
+fix the picture_start detection for multi-layer-mvc streams etc)
