This reverts commit 7fd14be804
The introduction of proper SD cards breaks the invariant that "external"
storage can be encrypted. Unfortunately, this means that accounts with
that policy bit set will have to be removed for now.
Accounts with the security policy set will be forced to go through
security provisioning on the next sync, using the regular mechanisms of
showing a notification with "Security update required", and then having
it fail. :(
