Set device.original_format to the new format in ActionCreateFormat

Original format should be always set to the "real" format for
existing devices. This normally happens in the StorageDevice
constructor but newly created devices have original_format always
set to DeviceFormat and require running reset to correct this which
can cause various issues when doing multiple do_it operations
without running reset between them.
