crypto: api - Add scaffolding to change completion function signature

The crypto completion function currently takes a pointer to a
struct crypto_async_request object.  However, in reality the API
does not allow the use of any part of the object apart from the
data field.  For example, ahash/shash will create a fake object
on the stack to pass along a different data field.

This leads to potential bugs where the user may try to dereference
or otherwise use the crypto_async_request object.

This patch adds some temporary scaffolding so that the completion
function can take a void * instead.  Once affected users have been
converted this can be removed.

The helper crypto_request_complete will remain even after the
conversion is complete.  It should be used instead of calling
the completion function directly.
