crypto: api - Disallow cryptomgr as a module if algorithms are built-in
If we have at least one algorithm built-in then it no longer makes sense to have the testing framework, and hence cryptomgr to be a module. It should be either on or off, i.e., built-in or disabled. This just happens to stop a potential runaway modprobe loop that seems to trigger on at least one distro. With fixes from Evgeniy Polyakov. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
