qemu: use g_autoptr for a virPCIDevice

The one instance of a virPCIDevice in
qemuDomainDeviceCalculatePCIConnectFlags() needs to be converted to
use g_autoptr as a prerequisite for a bugfix. It's in this patch by
itself (rather than in a patch converting all virPCIDevice usages to
g_autoptr) to simplify any backport of said bugfix.
