drm/gpusvm: Force unmapping on error in drm_gpusvm_get_pages
drm_gpusvm_get_pages() only sets the local flags prior to committing the
pages. If an error occurs mid-mapping, has_dma_mapping will be clear,
causing the unmap function to skip unmapping pages that were
successfully mapped before the error. Fix this by forcibly setting
has_dma_mapping in the error path to ensure all previously mapped pages
are properly unmapped.
