This allows supporting files for which the image stride is smaller than
the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file
or a 16x16 VP8 file with -fflags +emu_edge.

For cases when plugin does not return any samples we just return
input samples. Previously channel layout for outlink was not set.
Set it explicitly instead.

When av_reallocp fails, the associated variables that keep track of
the number of elements in the array (and in some cases, the
separate number of allocated elements) need to be reset.

Not all of these might technically be needed, but it's better to
reset them if in doubt, to make sure variables don't end up
conflicting.
