Jim Harris 0441ffcc05 nbd: do not free spdk_nbd_disk with io outstanding There is a race condition here, where kernel could have outstanding I/O to nbd device at the same time we terminate the nbd application. In this case, we cannot free the spdk_nbd_disk since it contains the io structure that will be referenced when the SPDK poller completes one of those I/O.

Jim Harris 0441ffcc05 nbd: do not free spdk_nbd_disk with io outstanding

There is a race condition here, where kernel could have
outstanding I/O to nbd device at the same time we terminate
the nbd application.  In this case, we cannot free the
spdk_nbd_disk since it contains the io structure that
will be referenced when the SPDK poller completes one
of those I/O.
