simple mistake in icmp payload calculation

The header offset that is calculated and then used to pickout the ports from the original datagram is wrong. One of the variables in the calculation is missing the "$". This obviously causes the ports to be incorrect.
here's the diff. ACID v0.9.6b21 acid_qry_alert.php 559c559 < $hdr_offset = ($work[$offset+1]) * 8 + offset; ---
$hdr_offset = ($work[$offset+1]) * 8 + $offset;
