Donglin Peng c9703d17d2 function_graph: Fix args pointer mismatch in print_graph_retval()
When funcgraph-args and funcgraph-retaddr are both enabled, many kernel
functions display invalid parameters in trace logs.

The issue occurs because print_graph_retval() passes a mismatched args
pointer to print_function_args(). Fix this by retrieving the correct
args pointer using the FGRAPH_ENTRY_ARGS() macro.
