vsock/virtio: fix kernel panic after device hot-unplug
[ Upstream commit 22b5c0b63f32568e130fa2df4ba23efce3eb495b ]
virtio_vsock_remove() invokes the vsock_core_exit() also if there
are opened sockets for the AF_VSOCK protocol family. In this way
the vsock "transport" pointer is set to NULL, triggering the
kernel panic at the first socket activity.
This patch move the vsock_core_init()/vsock_core_exit() in the
virtio_vsock respectively in module_init and module_exit functions,
that cannot be invoked until there are open sockets.
