[PATCH 3/5] drm/mediatek: Add initialization for mtk_gem_obj

[Jason-JH.Lin]

Calling mtk_gem_obj = kzalloc() which returns uninitialized memory,
because mtk_gem_obj is uninitialized.

It may cause using uninitialized value mtk_gem_obj->base.resv
when calling drm_gem_object_init().

So add initialization for mtk_gem_obj.
