crypto: api - Fix algorithm module auto-loading
The commit 89dd1d477cb68a6fb936b97560e1f85191b50d39 (crypto: api - Fix module load deadlock with fallback algorithms) broke the auto-loading of algorithms that require fallbacks. The problem is that the fallback mask check is missing an and which cauess bits that should be considered to interfere with the result.
