The last attempt version field describes the last firmware version for which
an update was attempted (uses the same format as Firmware Version).
Last Attempt Version is updated each time an UpdateCapsule() is attempted for
an ESRT entry and is preserved across reboots (non-). However, in
cases where the attempt version is not recorded due to limitations in the
update process, the field shall set to zero after a failed update. Similarly,
in the case of a removable device, this value is set to 0 in cases where the
device has not been updated since being added to the system.
