kernel: crypto: af_alg - zero initialize memory allocated via sock_kmalloc

A flaw was found in the Linux kernel's crypto AFALG subsystem. Memory allocated via sockkmalloc for crypto user API contexts is not zero-initialized, leaving fields with garbage values. Specifically, the 'inflight' variable can contain random data, causing afalgallocareq to spuriously return -EBU...
