[PATCH 5/5] ftrace: make filtered functions effective on setting

[Steven Rostedt]

Impact: set filtered functions at time the filter is set

It can be confusing when the set_filter_functions is set (or cleared)
and the functions being recorded by the dynamic tracer does not
match.

This patch causes the code to be updated if the function tracer is
enabled and the filter is changed.
