#1237321 — [for-next][PATCH 08/25] tracing: Turn seq_print_user_ip() into a static function

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

seq_print_user_ip() is used in only one location in one file. Turn it into a
static function. We could inject its code into the caller, but that would
make the code a bit too complex. Keep the code separate.
