Eric Biggers d4fdc2dfaa crypto: algapi - enforce that all instances have a ->free() method ...

All instances need to have a ->free() method, but people could forget to
set it and then not notice if the instance is never unregistered.  To
help detect this bug earlier, don't allow an instance without a ->free()
method to be registered, and complain loudly if someone tries to do it.
