MORITA Kazutaka 6d1acda8f1 sheepdog: fix co_recv coroutine context 
The co_recv coroutine has two things that will try to enter it:

  1. The select(2) read callback on the sheepdog socket.
  2. The aio_add_request() blocking operations, including a coroutine
     mutex.

This patch fixes it by setting NULL to co_recv before sending data.

In future, we should make the sheepdog driver fully coroutine-based
and simplify request handling.
