Summary:
If you rotate the FV2 Personal Key multiple times, it will eventually fail to rotate.

I've included an example script and password plist to help replicate this issue reliably.

Steps to Reproduce:
1. Run 'sudo ./break_filevault_rotation.rb
2. Wait
3. Key will stop rotating and will refuse to rotate until after a reboot.

Expected Results:
It should rotate without issue.

Actual Results:
Key fails to rotate

Version:
10.11.1 15B42
