Subject: [PATCH] function_graph: Fix missing FGRAPH_ENTRY_ARGS() call in print_graph_retval()

From: Donglin Peng <pengdonglin@...omi.com>

Call FGRAPH_ENTRY_ARGS(entry) to retrieve the correct arguments pointer
when displaying function parameters in print_graph_retval().

Fixes: f83ac7544fbf ("function_graph: Enable funcgraph-args and funcgraph-retaddr to work simultaneously")
