vsock: introduce vsock_pending_to_accept() helper
Add vsock_pending_to_accept() to move a socket directly from the
pending list to the accept queue in a single operation, avoiding
the sock_put/sock_hold dance and the sk_acceptq_removed()/
sk_acceptq_added() pair that would otherwise be needed when
calling vsock_remove_pending() followed by vsock_enqueue_accept().
Use it in vmci_transport_recv_connecting_server() where a completed
handshake transitions the socket from pending to accept queue.
