drm/i915/gt: Simplify shmem_create_from_object map_type selection

Browse Source 
The object pin created for shmem_create_from_object is just a
single use mapping with the sole purpose of reading the contents
of the whole object in bulk. And the whole source object is also
even a throw-away.  Ergo, the additional logic required by
i915_coherent_map_type can be safely dropped and simplified.
