migration: Skip only empty block devices
The block .save_setup() handler calls a helper routine
init_blk_migration() which builds a list of block devices to take into
account for migration. When one device is found to be empty (sectors
== 0), the loop exits and all the remaining devices are ignored. This
is a regression introduced when bdrv_iterate() was removed.
Change that by skipping only empty devices.
