Read disk identifier after config drive setup

Browse Source 
If original disk image has ID of 0x00000000 it's overwritten by parted
with a non-zero value. The original ID is stored in pxelinux.cfg/* config
file and the node fails to boot.

Reading the ID was moved to after config drive setup so that the final ID
is returned.
