Nicolin Chen b23e09f999 iommufd: Report unmapped bytes in the error path of iopt_unmap_iova_range 
There are callers that read the unmapped bytes even when rc != 0. Thus, do
not forget to report it in the error path too.

Fixes: 8d40205f60 ("iommufd: Add kAPI toward external drivers for kernel access")
