bpf, vsock: Invoke proto::close on close() 



vsock defines a BPF callback to be invoked when close() is called. However,
this callback is never actually executed. As a result, a closed vsock
socket is not automatically removed from the sockmap/sockhash.

Introduce a dummy vsock_close() and make vsock_release() call proto::close.

Note: changes in __vsock_release() look messy, but it's only due to indent
level reduction and variables xmas tree reorder.
