[Intel-gfx] [PATCH v12 07/11] drm/shmem-helper: Remove obsoleted is_iomem test

[Dmitry Osipenko <dmitry.osipenko@collabora.com>]

Everything that uses the mapped buffer should by agnostic to is_iomem.
The only reason for the is_iomem test is is that we're setting shmem->vaddr
to the returned map->vaddr. Now that the shmem->vaddr code is gone, remove
the obsoleted is_iomem test to clean up the code.
