translate_sse: Use the correct buffer index in this fast path.
It is possible that there are multiple input buffers but only one is
relevant for translation. Then there will be only a single translation
group, which might need to source data from a buffer index != 0.
Fixes wrong vertex shader inputs as observed while debugging with an
application and driver combination that requires translation of a
vertex attribute in a non-trivial set of attributes and input buffers.
