Subject: [PATCH] avcodec/vp9mvs: fix misaligned access when clearing VP9mv
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes runtime error: member access within misaligned address
<addr> for type 'av_alias64', which requires 8 byte alignment.

VP9mv is aligned to 4 bytes, so instead doing 8 bytes clear, let's do
2 times 4 bytes.
