dnsmasq: Fix hosts file format when MAC address is not specified
An entry like this in /etc/config/dhcp:
config 'host'
option 'name' 'pc2'
option 'ip' '192.168.100.56'
option 'dns' '1'
results in a /tmp/hosts/dhcp entry that looks like this:
192.168.100.56 .lan
Obviously it should say "pc2.lan".
This happens because $name is set to "" in order to support the MAC-less
syntax: "--dhcp-host=lap,192.168.0.199". Fix this by reordering the
operations. Also, refuse to add a DNS entry if the hostname or IP is
missing.
Fixes #17683
