vpbroadcastb and vpbroadcastd are not AVX instructions.
But the aria-avx assembly code contains these instructions.
So, kernel panic will occur if the aria-avx works on AVX2 unsupported
CPU.
vbroadcastss, and vpshufb are used to avoid using vpbroadcastb in it.
Unfortunately, this change reduces performance by about 5%.
Also, vpbroadcastd is simply replaced by vmovdqa in it.
Fixes: ba3579e6e4 ("crypto: aria-avx - add AES-NI/AVX/x86_64/GFNI assembler implementation of aria cipher")
