block/nbd: nbd_co_reconnect_loop(): don't connect if drained
In a recent commit 12c75e20a269ac we've improved
nbd_co_reconnect_loop() to not make drain wait for additional sleep.
Similarly, we shouldn't try to connect, if previous sleep was
interrupted by drain begin, otherwise drain_begin will have to wait for
the whole connection attempt.
