[PATCH 4/7] drm/i915: Sanitize i915_gem_load() init and clean-up

[Imre Deak <imre.deak@xxxxxxxxx>]

Factor out common clean-up code for the GEM load time init function.
Also rename i915_gem_load() to i915_gem_load_init() to have a better
match with its new clean-up function.

No functional change.
