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.
