[libvirt] [PATCH v6 5/9] nodedev: udev: Unlock the private data before setting up 'system' node
udevSetupSystemDev only needs the udev data lock to be locked because of
calling udevGetDMIData which accesses some protected structure members,
but it can do that on its own just fine, no need to hold the lock the
whole time.
