Subject: [PATCH] RHEL: qemu: Alter @val usage in qemuSetUnprivSGIO
MIME-Version: 1.0

https://bugzilla.redhat.com/show_bug.cgi?id=1656360 (RHEL7)
RHEL-only
Rather than initializing to -1 and then setting to the result
of a boolean check (either 0 or 1), let's just initialize @val
to 0 and then only change to 1 if conditions are "right".
