[for-next][PATCH 01/15] ftrace: Add back ftrace_update_trampoline() to ftrace_update_pid_func()

[Steven Rostedt]

From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>

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