ipfw - Fix broken mixed network and host IP specifications in ip tables
* ipfw improperly assumes that the netmask sin_len is pre-zero'd, but
prior table entries on the same command line which specify a network
mask will leave the field non-zero for later host entries also specified
on the command line:
ipfw table 1 add 10.0.0.0/8 192.0.2.1 # 2^24 + 1 addresses
# ipfw table 1 print
10.0.0.0/8
192.0.0.0/8 <--- wrong
* Fix the issue by properly initializing netmask.sin_len to 0 when a
host IP is specified.
