net: ipconfig: Don't override command-line hostnames or domains
[ Upstream commit b508d5fb69c2211a1b860fc058aafbefc3b3c3cd ]
If the user specifies a hostname or domain name as part of the ip=
command-line option, preserve it and don't overwrite it with one
supplied by DHCP/BOOTP.
For instance, ip=::::myhostname::dhcp will use "myhostname" rather than
ignoring and overwriting it.
Fix the comment on ic_bootp_string that suggests it only copies a string
"if not already set"; it doesn't have any such logic.
