function_graph: Remove the unused variable func 

Variable func is not effectively used, so delete it.

kernel/trace/trace_functions_graph.c:925:16: warning: variable ‘func’ set but not used.

This happened because the variable "func" which came from "call->func" was
replaced by "ret_func" coming from "graph_ret->func" but "func" wasn't
removed after the replacement.
