crypto: skcipher - Add default key size helper
While converting ecryptfs over to skcipher I found that it needs to pick a default key size if one isn't given. Rather than having it poke into the guts of the algorithm to get max_keysize, let's provide a helper that is meant to give a sane default (just in case we ever get an algorithm that has no maximum key size).
