Matt Caswell b533510f3b Fail if we fail to fetch the EVP_KEYMGMT 
If we failed to fetch an EVP_KEYMGMT then we were falling back to legacy.
This is because some algorithms (such as MACs and KDFs used via an old
style EVP_PKEY) have not been transferred to providers.

Unfortunately this means that you cannot stop some algorithms from being
used by not loading the provider.

For example if you wanted to prevent RSA from being used, you might expect
to just not load any providers that make it available. Unfortunately that
doesn't work because we simply fall back to legacy if we fail to fetch
the EVP_KEYMGMT.

Instead we should fail *unless* the key type is one of those legacy key
types that we have not transferred.
