Subject: [PATCH] ftrace: Add back ftrace_update_trampoline() to
 ftrace_update_pid_func()

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

The update to the ops trampoline done by the function
ftrace_update_trampoline() was accidentally removed from
ftrace_update_pid_func(). Add it back.

Fixes: df3ec5da6a1e ("function_graph: Add pid tracing back to function graph tracer")
