Commit 24be92b8e moved the option rom settings validation code to the validation callbacks, but that doesn't work properly with device hotplug as we assign addresses only after parsing the whole XML. The check is too strict for that and caused failures when hotplugging devices such as: <interface type='network'> <source network='default'/> <model type='virtio'/> <rom enabled='no'/> </interface> This patch relaxes the check in the validation callback to accept also _NONE and _UNASSIGNED address types and returns the check to 'qemuBuildRomProps' so that we preserve the full validation as we've used to.
