4.19-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 1b275e4e8b70dbff9850874b30831c1bd8d3c504 ]
Fix the assigned type of mem2mem buffer handling API. Namely, these functions:
v4l2_m2m_next_buf v4l2_m2m_last_buf v4l2_m2m_buf_remove v4l2_m2m_next_src_buf v4l2_m2m_next_dst_buf v4l2_m2m_last_src_buf v4l2_m2m_last_dst_buf v4l2_m2m_src_buf_remove v4l2_m2m_dst_buf_remove
return a struct vb2_v4l2_buffer, and not a struct vb2_buffer.
Fixing this is necessary to fix the mem2mem buffer handling API, changing the return to the correct struct vb2_v4l2_buffer instead of a void pointer.
