Zone Descriptor Extension is a label that can be assigned to a zone. It can be set to an Empty zone and it stays assigned until the zone is reset. This commit adds a new optional module property, "zoned.descr_ext_size". Its value must be a multiple of 64 bytes. If this value is non-zero, it becomes possible to assign extensions of that size to any Empty zones. The default value for this property is 0, therefore setting extensions is disabled by default.
