crypto: api - Fix algorithm module auto-loading
The commit a760a6656e6f00bb0144a42a048cf0266646e22c (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.
