[PATCH 2/7] block/nbd: Delete open timer when done

[Hanna Reitz]

We start the open timer to cancel the connection attempt after a while.
Once nbd_do_establish_connection() has returned, the attempt is over,
and we no longer need the timer.

Delete it before returning from nbd_open(), so that it does not persist
for longer.  It has no use after nbd_open(), and just like the reconnect
delay timer, it might well be dangerous if it were to fire afterwards.
