ftrace: fix "notrace" filtering priority
This is a fix to give notrace filter rules priority over "set_ftrace_filter"
rules.
This fix ensures that functions which are set to be filtered and are
concurrently marked as "notrace" don't get recorded. As of now, if
a record is marked as FTRACE_FL_FILTER and is enabled, then the notrace
flag is not checked. Tested on x86-32.
