module/zstd: pass -U__BMI__
If kernel is compiled with -march=znver1 or -march=znver2 zstd module
compilation will fail due to SSE register return with SSE disabled.
What's interesting, is that -march=skylake also implies -mbmi which
defines __BMI__ but compilation succeeds. It is probably due to
different BMI implementations on AMD and INTEL processors and the
way compiler uses instructions.
