BUG/MINOR: backend: only match IPv4 addresses with RDP cookies

The RDP cookie extractor compares the 32-bit address from the request
to the address of each server in the farm without first checking that
the server's address is IPv4. This is a leftover from the IPv4 to IPv6
conversion. It's harmless as it's unlikely that IPv4 and IPv6 servers
will be mixed in an RDP farm, but better fix it.

This patch does not need to be backported.
