nbd/server: Advertise all contexts in response to bare LIST
The NBD spec, and even our code comment, says that if the client asks for NBD_OPT_LIST_META_CONTEXT with 0 queries, then we should reply with (a possibly-compressed representation of) ALL contexts that we are willing to let them try. But commit 3d068aff forgot to advertise qemu:dirty-bitmap:FOO.
