[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.
