tcp: Fix address type for tcp_sock_init_af()

Browse source 
This takes a struct in_addr * (i.e. an IPv4 address), although it's
explicitly supposed to handle IPv6 as well.  Both its caller and sock_l4()
which it calls use a void * for the address, which can be either an in_addr
or an in6_addr.

We get away with this, because we don't do anything with the pointer other
than transfer it from the caller to sock_l4(), but it's misleading.  And
quite possibly technically UB, because C is like that.
