[Mesa-dev] [PATCH 03/10] panfrost: Get rid of the "free imported BO" logic

[Boris Brezillon]

bo->imported was never set to true which means this path was never taken.
Moreover, panfrost_drm_free_imported_bo() is doing missing the munmap()
call which seems wrong because the import BO function calls mmap().

Let's just kill this function along with the ->imported field.
