Subject: [PATCH] block: restart partition scan after resizing a device

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.
