sink-input: fix rewriting render memblockq when nothing should be rewound

Browse source 
If process_rewind() is called with nbytes = 0, process_rewind() will
nevertheless request a rewrite of the render memblockq.

This patch fixes the problem by adding the render memblockq length to the
rewrite amount only if nbytes > 0.
