[PATCH 1/6] i2c: put driver_unregister() out of core_lock protection.

[Rodolfo Giometti <giometti-k2GhghHVRtY@public.gmane.org>]

As for i2c_register_driver() during driver registration only
class_for_each_device() call is protected by the i2c "core_lock" so we
can (hopefully) do the same during driver deletion.
