drm/i915: Propagate error from drm_gem_object_init()
Propagate the real error from drm_gem_object_init(). Note this also
fixes some confusion in the error return from i915_gem_alloc_object...
v2:
(Matthew Auld)
- updated new users of gem_alloc_object from latest drm-nightly
- replaced occurrences of IS_ERR_OR_NULL() with IS_ERR()
v3:
(Joonas Lahtinen)
- fix double "From:" in commit message
- add goto teardown path
v4:
(Matthew Auld)
- rebase with i915_gem_alloc_object name change
