the exit field should not be used in entry list

Hello Steve,

The entry list is applied to match fields before excuting syscall. When matching, the exit code of syscall is unknown. So the exit field should not be used in entry list.
This is a patch for latest audit-1.7.4.

Hi,

Looks good. Applied. I also checked the code in libaudit.c and fixed it to do the same thing. Thanks for the patch.
