> Device resize via ->set_capacity() can reveal new partitions (e.g. in
> chained partition table formats such as dos extended parts).  Restart
> partition scan from the beginning after resizing a device.  This
> change also makes libata always revalidate the disk after resize which
> makes lower layer native capacity unlocking implementation simpler and
> more robust as resize can be handled in the usual path.
