gallium/tgsi_exec: Fix up NumOutputs counting

We can get duplicate declarations for an index (for example dvec3 + float
packed into 2 vec4s, the second one won't pack into the first's array
decl), and we'd end up stepping by the wrong amount in GS vtx/prim emit.

Fixes vs-gs-fs-double, sso-vs-gs-fs-array-interleave piglit tests.
