Instead of discovering the ID of the device and call two different functions for a block device or a partition, we can rewrite efi_disk_remove() and handle the minor differences between the two variants internally. As a results we can simplify efi_disk_remove() a lot and get rid of the extra efi_disk_delete_raw/blk calls.
