audit: add refused symlink to audit_names

Audit link denied events for symlinks had duplicate PATH records rather
than just updating the existing PATH record.  Update the symlink's PATH
record with the current dentry and inode information.

See: https://github.com/linux-audit/audit-kernel/issues/21
