Update bdev_capacity to have wholedisk vdevs query the size of the underlying block device (correcting for the size of the efi parition and partition alignment) and therefore detect expanded space. Correct vdev_get_stats_ex so that the expandsize is aligned to metaslab size and new space is only reported if it is large enough for a new metaslab.
