[Canary] Failed at autoupdate_EndToEndTest.paygen_au_canary_full on devices which moved from 3.10 to 4.4 kernel

What the issue was:
autoupdate_EndToEndTest.paygen_au_canary_full failed and the DUTs were no longer pingable after the failure of udpate_stateful(). This issue is caused by enabling the encryption on file system where the devices need power wash to wipe stateful. Since some devices were moved from kernel 3.10 to 4.4 where 3.10 doesn't support encryption feature while 4.4 does. The move happened during M57/M58.

Gwendal is investigating and will update the bug.

Testing on glimmer.
I haven't found the root cause yet. 3.10 kernel it not crashing when presented a ext4 fs with encryption failure, it nicely reject the mount. I also verified e4crypt tool is failing nicely.
However, the kernel crashes in loop at boot with a "attempted to kill init" kernel panic. I would have expected a rollback in the lab.

Given glimmer moved to 4.4 1/17 and direncryption was added 3/17, a possible the stepping stone is in a narrow window.
