crypto: shash - require neither or both ->export() and ->import()

Prevent registering shash algorithms that implement ->export() but not
->import(), or ->import() but not ->export().  Such cases don't make
sense and could confuse the check that shash_prepare_alg() does for just
->export().

I don't believe this affects any existing algorithms; this is just
preventing future mistakes.
