[libvirt] [PATCH v6 4/9] nodedev: udev: Remove driver locks from stateInitialize and stateCleanup

[Erik Skultety]

The driver locks are unnecessary here, since currently the cleanup is
only called from the main daemon thread, so we can't race here. Moreover
@devs and @privateData are self-lockable objects, so no problem there
either.
