Behan Webster 37e5265437 crypto: LLVMLinux: Remove VLAIS from crypto/.../qat_algs.c
Replaced the use of a Variable Length Array In Struct (VLAIS) with a C99
compliant equivalent. This patch allocates the appropriate amount of memory
using a char array using the SHASH_DESC_ON_STACK macro.

The new code can be compiled with both gcc and clang.
