tcp, tcp_splice: Avoid double layered dispatch for connected TCP sockets

Currently connected TCP sockets have the same epoll type, whether they're
for a "tap" connection or a spliced connection.  This means that
tcp_sock_handler() has to do a secondary check on the type of the
connection to call the right function.  We can avoid this by adding a new
epoll type and dispatching directly to the right thing.
