nbd: Consistently use request pointer in debug messages.
Browse files Browse the repository at this point in the history
Existing dev_dbg messages sometimes identify request using request
pointer, sometimes using nbd_cmd pointer. This makes it hard to
follow request flow. Consistently use request pointer instead.
