[for-next][PATCH 2/2] function_graph: Remove unnecessary initialization in ftrace_graph_ret_addr()

[Steven Rostedt]

From: Oleg Nesterov <oleg@xxxxxxxxxx>

After the commit 29c1c24a2707 ("function_graph: Fix up ftrace_graph_ret_addr()")
ftrace_graph_ret_addr() doesn't need to initialize "int i" at the start.
