[Patch]Fix the bug of using "-S syscall -a list, action", no errors will be reported.



Hi Steve,

  When I use "-a user,always -S open", errors will be reported. But when I use
"-S open -a user,always", no errors will report. There is no corresponding
codes to deal with the later format.

  Here is my patch. Hope for your opinion about such modification.
  (I move the code for checking "task" list to the handle_request().)
