Given Jan's comments about the overall series, I'd like to propose
squashing in the attached patch into this patch.  Essentially it's
making the same check and returning 0 if the shared bit wasn't set. The
current code checks for shared hostdev *and* sgio is set, then fail;
otherwise, return 0.  This patch will check shared hostdev, return 0 if
not.. then check sgio singularly and fail; otherwise return 0.
