Correct kernel-doc warnings in i915_drm_object.c:

i915_gem_object.c:103: warning: expecting prototype for i915_gem_object_fini(). Prototype was for __i915_gem_object_fini() instead
i915_gem_object.c:110: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * Mark up the object's coherency levels for a given cache_level
i915_gem_object.c:110: warning: missing initial short description on line:
 * Mark up the object's coherency levels for a given cache_level
i915_gem_object.c:457: warning: No description found for return value of 'i915_gem_object_read_from_page'
