vkd3d-shader: Don't fetch output variable id before writing output info.

Otherwise, if a private variable is used for the given output,
vkd3d_dxbc_compiler_emit_store_shader_output will write to the
private variable again instead of the actual output, and some
outputs may never be emitted. This is common in hull shaders.
