The radv_emit_ngg_culling_state function won't write the
SPI_SHADER_PGM_RSRC2_GS register when it knows in advance that
radv_emit_graphics_pipeline will overwrite it anyway.
However, there is an unhandled case:
radv_emit_graphics_pipeline will not emit anything (including this
register) when the pipeline is already emitted. Hence, improve
the check in radv_emit_ngg_culling_state to consider this.
