ftrace: Change filter/notrace set functions to return exit code
Currently the ftrace_set_filter and ftrace_set_notrace functions
do not return any return code. So there's no way for ftrace_ops
user to tell wether the filter was correctly applied.
The set_ftrace_filter interface returns error in case the filter
did not match:
# echo krava > set_ftrace_filter
bash: echo: write error: Invalid argument
Changing both ftrace_set_filter and ftrace_set_notrace functions
to return zero if the filter was applied correctly or -E* values
in case of error.
