When parsing the nvlist for a struct pf_addr_wrap we unconditionally
tried to parse "ifname". This broke for PF_ADDR_TABLE when the table
name was longer than IFNAMSIZ. PF_TABLE_NAME_SIZE is longer than
IFNAMSIZ, so this is a valid configuration.
Only parse (or return) ifname or tblname for the corresponding
pf_addr_wrap type.
This manifested as a failure to set rules such as these, where the pfctl
optimiser generated an automatic table:
pass in proto tcp to 192.168.0.1 port ssh
pass in proto tcp to 192.168.0.2 port ssh
pass in proto tcp to 192.168.0.3 port ssh
pass in proto tcp to 192.168.0.4 port ssh
pass in proto tcp to 192.168.0.5 port ssh
pass in proto tcp to 192.168.0.6 port ssh
pass in proto tcp to 192.168.0.7 port ssh
