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.
