[PATCH] nbd: Abort request on data reception failure
When reading from nbd device, we need to receive all the data after receiving reply packet from the server - otherwise such request will never be ended. If socket is closed right after accepting reply control packet and in the middle of waiting for read data, nbd_read_stat() returns NULL and nbd_end_request() is not called. This patch fixes it.
