tracing: Make filter_check_discard() local
Nothing outside of the tracing directory calls filter_check_discard() or check_filter_check_discard(). They should not be called by modules. Move their prototypes into the local tracing header and remove their EXPORT_SYMBOL() macros. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
