Subject: dm: suspend: fix error path
From: Alasdair G Kergon <agk@xxxxxxxxxx>
If the device is already suspended, just return the error and skip the code
that would incorrectly wipe md->suspended_bdev.
(This isn't currently a problem because existing code avoids calling this
function if the device is already suspended.)
