Subject: [PATCH] qemu: Alter qemuSetUnprivSGIO hostdev shareable logic

Fix the logic to handle the case where if the <shareable/> element
|
|
was removed from the domain <hostdev.../>, then we have to reset the
|
|
SGIO value back to 0. Without this patch the check for not shareable
|
|
and return 0 would bypass resetting the value back to 0.
