[17.1.5] floating rule with a dest port range with a start value but no end value is valid

[sjorge]

You can create a floating rule with a destination range starting at X and with no value in the end.
This results in 'any' port.

I was trying to something like this:
source $localnets
source_port *
dest *
dest_port 32400 - 32415

But accidently created
source $localnets
source_port *
dest *
dest_port 32400 -

Which resulted in this rule being added:
pass in quick on { vtnet1 vtnet3 vtnet2 } inet proto tcp from $localnets to any flags S/SA label "USER_RULE: "

Just tested the patch, looks good!
