rxrpc: Use IPv4 addresses throught the IPv6
AF_RXRPC opens an IPv6 socket through which to send and receive network packets, both IPv6 and IPv4. It currently turns AF_INET addresses into AF_INET-as-AF_INET6 addresses based on an assumption that this was necessary; on further inspection of the code, however, it turns out that the IPv6 code just farms packets aimed at AF_INET addresses out to the IPv4 code. Fix AF_RXRPC to use AF_INET addresses directly when given them. Fixes: 7b674e390e51 ("rxrpc: Fix IPv6 support") Signed-off-by: David Howells <dhowells@redhat.com>
