crypto: mark xts(aes) as fips_allowed

We (Red Hat) are intending to include dm-crypt functionality, using xts(aes) for disk encryption, as part of an upcoming FIPS-140-2 certification effort, and xts(aes) *is* on the list of possible mode/cipher combinations that can be certified. To make that possible, we need to mark xts(aes) as fips_allowed in the crypto subsystem.

A 'modprobe tcrypt mode=10' in fips mode shows xts(aes) self-tests passing successfully after this change.
