c 6ada3be8f1 net: Reject invalid characters in port ranges
Fixes issue #22469 where port strings such as '0x00' get accepted, not
because the string gets converted to hex, but because the string is
silently truncated past the invalid character 'x'. This also causes
issues for strings such as '0x01-0x02' which look like a hex port range,
but in reality gets truncated to '0', which is definitely not what a
user intends.

Warn and reject such port strings as invalid.

Also, since we're throwing that "malformed port" warning a lot in the
function, wrap it up in a nice goto.

Fixes #22469
