pflog(4) logs packet dropped by default rule with block.

pflog(4) logs packet dropped by default rule with block.

If a packet is malformed, it is dropped by pf(4).  The rule referenced
in pflog(4) is the default rule.  As the default rule is a pass
rule, tcpdump printed "pass" although the packet was actually
dropped.  To avoid confusion, change the action to drop.  Then
tcpdump prints "block".
