Ingo Molnar b54b4bbbf5 x86/fpu, crypto: Fix AVX2 feature tests 
For some CPU models I broke the AVX2 feature detection in:

  7bc371faa9 ("x86/fpu, crypto x86/camellia_aesni_avx2: Simplify the camellia_aesni_init() xfeature checks")
  534ff06e39 ("x86/fpu, crypto x86/serpent_avx2: Simplify the init() xfeature checks")

... because I did not realize that it's possible for a CPU to support
the xstate necessary for AVX2 execution (XSTATE_YMM), but not have
the AVX2 instructions themselves.

Restore the necessary CPUID checks as well.
