media: mtk-vcodec: fix access to incorrect planes member
Commit 0650a91499e0 ("media: mtk-vcodec: Correct return type for mem2mem
buffer helpers") fixed the return types for mem2mem buffer helper
functions by changing a few local variables from vb2_buffer to
vb2_v4l2_buffer. However, it left a few accesses to vb2_buffer::planes
as-is, accidentally turning them into accesses to
vb2_v4l2_buffer::planes and resulting in values being read from/written
to the wrong place.
Fix this by inserting vb2_buf into these accesses so they mimic their
original behavior.
