Lorenzo Colitti adfa7bc8b4 tcp: Don't nuke connections for the wrong protocol 
Currently, calling tcp_nuke_addr to reset IPv6 connections
resets IPv4 connections as well, because all Android
framework sockets are dual-stack (i.e., IPv6) sockets, and
we don't check the source address to see if the connection
was in fact an IPv4 connection.

Fix this by checking the source address and not resetting
the connection if it's a mapped address.

Also slightly tweak the IPv4 code path, which doesn't check
for mapped addresses either. This was not causing any
problems because tcp_is_local normally always returns true
for LOOPBACK4_IPV6 (127.0.0.6), because the loopback
interface is configured as as 127.0.0.0/8. However,
checking explicitly for LOOPBACK4_IPV6 makes the code a bit
more robust.
