fs: cifs: move from the crypto cipher API to the new DES library interface
Some legacy code in the CIFS driver uses single DES to calculate some password hash, and uses the crypto cipher API to do so. Given that there is no point in invoking an accelerated cipher for doing 56-bit symmetric encryption on a single 8-byte block of input, the flexibility of the crypto cipher API does not add much value here, and so we're much better off using a library call into the generic C implementation.
