Revert "drm/i915: Unreference object not handle on creation"
This reverts commit 86f100b136626e91f4f66f3776303475e2e58998. The kref API requires the handlecount to be initialised to one on object creation (so that kref_get() doesn't complain upon first use) so the dalliance in the drivers is required in order to sink the initial floating reference.
