[libvirt] [PATCH] lxc: Rearrange order in lxcDomainUpdateDeviceFlags
Although commit e3497f3f noted that the LIVE option doesn't
matter and removed the call to virDomainDefCompatibleDevice,
it didn't go quite far enough and change the order of the checks.
Since we don't have the possibility of LIVE succeeding and thus
the need for a delayed update in order to write the CONFIG change
let's just merge the saving of the config into one if statement.
