FS_IOC_GET_ENCRYPTION_POLICY_EX allows filesystem encryption users to
retrieve the encryption policy for files and directories that use a v2
encryption policy.  Unlike the original FS_IOC_GET_ENCRYPTION_POLICY,
FS_IOC_GET_ENCRYPTION_POLICY_EX is also extensible to new versions of
the policy struct that may be added in the future.
