Subject: [PATCH] gallium/auxiliary/vl: fix typo which negatively impacts the
 src_stride initialization

Note: As a matter of fact, this change by itself makes vdpau on r600 works again.
Indeed, r600 sets the stride value with vertex_buffer_index as the r600 index;
vertex_buffer_index was set to zero at the vl_compositor/init_buffers() stage on
the three elements. As a consequence of this typo the stride value was overwritten
to zero. This was breaking vdpau.
