David Gibson 233b95e90f tcp: Remove splice from tcp_epoll_ref
Currently the epoll reference for tcp sockets includes a bit indicating
whether the socket maps to a spliced connection.  However, the reference
also has the index of the connection structure which also indicates whether
it is spliced.  We can therefore avoid the splice bit in the epoll_ref by
unifying the first part of the non-spliced and spliced handlers where we
look up the connection state.
