VSOCK: defer sock removal to transports
The virtio transport will implement graceful shutdown and the related
SO_LINGER socket option. This requires orphaning the sock but keeping
it in the table of connections after .release().
This patch adds the vsock_remove_sock() function and leaves it up to the
transport when to remove the sock.
