[Qemu-devel] [PULL 13/27] nbd: Rename struct nbd_request and nbd_reply

[Paolo Bonzini <pbonzini@redhat.com>]

From: Eric Blake <eblake@redhat.com>

Our coding convention prefers CamelCase names, and we already
have other existing structs with NBDFoo naming.  Let's be
consistent, before later patches add even more structs.
