Revert of Clean up Smart Lock cryptohome keys logic: (patchset #5 id:80001 of https://codereview.chromium.org/808563004/)

Reason for revert:
Once this change landed chromeos file manager tests started failing across the MSAN bots.

This is the most likely culprit, so reverting speculatively. If this does not help will reland this change.
