./net/net.c - make Microsoft dns servers happy with random_port() numbers

For some reason, (which I can't find any documentation on), if U-Boot
gives a port number higher than 17500 to a Microsoft DNS server, the
server will reply to port 17500, and U-Boot will ignore things (since
that isn't the port it asked the DNS server to reply to).

This fixes that by ensuring the random port number is less than 17500.
