If a later page failed (e.g. -EOPNOTSUPP when ctx->allow_mixed is false) and jumped to err_unmap, svm_pages->dpagemap was still NULL, so __drm_gpusvm_unmap_pages() skipped device_unmap() and leaked the device mappings already created. Assign svm_pages->dpagemap when the first device page is mapped so the err_unmap path can device_unmap() those mappings. This issue was found by Sashiko AI review.
