Two small errors in ausearch-parse.c

[Emily Ratliff]

While testing usage of some tools, I stumbled across two small errors in
ausearch-parse.c. I have attached two patches
end-fix.patch fixes the segfaults which can be found by running
ausearch -m USER_AUTH,USER_ACCT --success no --if end-986-dump.log
and
ausearch -m USER_AUTH,USER_ACCT --success no --if error-ausearch.log

term-segfault.patch fixes the errors that can be found by running
aureport -if corrupt-log-for-aureport.log
and
ausearch -m USER_AUTH,USER_ACCT --success no --if
corrupt-log-for-ausearch.log

The erroneous log files were produced using zzuf. The corrupted log files
are also attached. It is unlikely that a user will encounter corrupted
audit log files in the wild, so these bugs aren't serious, but they are
easy to fix.
