668b0cf939 deinterlace: Clean up error handling in chain and _push_history 
- Consistently unref the chained buffer at the end of the chain
  function, if we're not handing it off to `gst_pad_push`. This avoids a
  few buffer leaks in the error paths in `_chain` and `_push_history`.
- When mapping the video frame fails, return a flow error instead of
  crashing.

832367c58e deinterlace: scalerbob: Reduce latency to 0 
We only need the current field, just like `linear`.

4b41af5d65 deinterlace: Prevent race between _set_method and latency query 
It's possible that the method is being manipulated while downstream
queries our latency, leading to crashes.

Prevent that from happening.

8f31e0c42a yadif.asm: Fix improper usage of LOAD macro 
LOAD macro relies in m7 being zero for interleaving purposes. Using LOAD
on the m7 register makes it interleave with its new content instead of
with 0.

The effect of this bug was bobbing on some static lines that appeared
over fast-moving content.

b8cbcf44d7 yadif: Fix bug in C implementation of CHECK 
It was different compared to the corresponding part in both ffmpeg and
the asm implementation. Fixing this makes videotestsrc pattern=spokes
not jump at all when not using the asm optimisations.

53def214fa deinterlace: greedyh: Use _plane in _packed, fix planar formats 
This greatly reduces code duplication. It also exposed the cause for
planar formats not being properly deinterlaced:

The planar path was missing the initial offset adjustment that the
packed path did to `L2` and `L2P` in the case of an even field, which
caused it to select the wrong weave lines every other field.

Add those offsets in `_plane`.
