[patch 18/20] swsusp: Fix swap_type_of

[Greg KH]

-stable review patch.  If anyone has any objections, please let us know.

------------------
From: "Rafael J. Wysocki" <rjw@xxxxxxx>

There is a bug in mm/swapfile.c#swap_type_of() that makes swsusp only be
able to use the first active swap partition as the resume device.  Fix it.
