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. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1823>
