drm/shmem-helper: Remove obsoleted is_iomem test
commit eab10538073c3ff9e21c857bd462f79f2f6f7e00 upstream.
Everything that uses the mapped buffer should be agnostic to is_iomem.
The only reason for the is_iomem test 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.
