nvptx: Silence unused variable warning in output_constant_pool_contents()

Similar to the rs6000 code, nvptx defines ASM_OUTPUT_DEF_FROM_DECLS as well as
ASM_OUTPUT_DEF. Make sure that the define's parameters are used by referencing
them as (void) to silence a warning in output_constant_pool_contents().
