Jim Harris f176436b69 test/bdev: wait for nbd device to become ready
Previously, we were waiting to find the target bdev as
registered before proceeding with nbd operations.  But
there can be a delay between when the bdev is registered
and when the nbd device becomes ready for block I/O
operations.  This delay has recently become longer as
lvol now performs I/O on registered bdevs to check for
an existing logical volume store.

So instead, check for the existence of the nbd device
in /proc/partitions output.

While here, also fix a bug in the nbd.c code - it needs
to wait for the poller to be unregistered before calling
spdk_nbd_stop().  Normally I would fix this in a separate
patch but because these issues are causing a lot of
failures in the test pool, I'm expediting this by putting
both fixes in one patch (so we can avoid a bunch of
re-runs).
