ftrace: Assign RCU list variable with rcu_assign_ptr()
Use rcu_assign_ptr() to assign the list pointer as it is marked as RCU,
and this quiets the sparse warning:
kernel/trace/ftrace.c:313:23: warning: incorrect type in assignment (different address spaces)
kernel/trace/ftrace.c:313:23: expected struct ftrace_ops [noderef] __rcu *
kernel/trace/ftrace.c:313:23: got struct ftrace_ops *
