[PATCH] mport match port parsing broken: fix

[Daniel Roethlisberger]

mport match parse_port() fix

The mport match extension was broken in iptables-1.2.3 and CVS:
all ports and ranges were always parsed as port number 1. The
return value of string_to_number was assigned to portnum, even
though string_to_number returns the result via the fourth pointer
argument, and not as return value.

Cheers,
Dan
