Mark O'Donovan 32445526d8 nvme-auth: allow mixing of secret and hash lengths
We can now use any of the secret transformation hashes with a
secret, regardless of the secret size.
e.g. a 32 byte key with the SHA-512(64 byte) hash.

The example secret from the spec should now be permitted with
any of the following:
DHHC-1:00:ia6zGodOr4SEG0Zzaw398rpY0wqipUWj4jWjUh4HWUz6aQ2n:
DHHC-1:01:ia6zGodOr4SEG0Zzaw398rpY0wqipUWj4jWjUh4HWUz6aQ2n:
DHHC-1:02:ia6zGodOr4SEG0Zzaw398rpY0wqipUWj4jWjUh4HWUz6aQ2n:
DHHC-1:03:ia6zGodOr4SEG0Zzaw398rpY0wqipUWj4jWjUh4HWUz6aQ2n:

Note: Secrets are still restricted to 32,48 or 64 bits.
