[Suspend2][ 07/28] [Suspend2] Reset swapwriter when not resuming.

[Nigel Cunningham <nigel@suspend2.net>]

Reset the device info and close bdevs when we set up when preparing to
resume. This might happen because of a problem, or because noresume2 was
given on the command line and we needed first to invalidate the image.
