#3 Get rid of: type qualifiers ignored on function return type [-Wignored-qualifiers]

[Michael Nix]

When compiling, I get the warning: type qualifiers ignored on function return type [-Wignored-qualifiers]

This is caused by a const qualifier for CryptGetHashDef. The warning (as I understand it) means, that it can't be guaranteed that the returned type is always const. So it might as well be removed.

Proposed changes:

Someone else found this as well. It's that PHASH_DEF is already a const. It doesn't cause any TPM malfunction, but it will be fixed.
