Subject: fade: make draw_slice() chroma check against planes 1 and 2

fade: make draw_slice() chroma check against planes 1 and 2

draw_slice() checks that planes 0 and 1 of AVFilterBufferRef's data
are not NULL before manipulating planes 1 and 2. This patch makes the
check against planes 1 and 2. More senseful and possibly more robust.
