Josh Poimboeuf 0e14ef3866 crypto: x86/sm4 - Fix frame pointer stack corruption 
sm4_aesni_avx_crypt8() sets up the frame pointer (which includes pushing
RBP) before doing a conditional sibling call to sm4_aesni_avx_crypt4(),
which sets up an additional frame pointer.  Things will not go well when
sm4_aesni_avx_crypt4() pops only the innermost single frame pointer and
then tries to return to the outermost frame pointer.

Sibling calls need to occur with an empty stack frame.  Do the
conditional sibling call *before* setting up the stack pointer.

This fixes the following warning:

  arch/x86/crypto/sm4-aesni-avx-asm_64.o: warning: objtool: sm4_aesni_avx_crypt8()+0x8: sibling call from callable instruction with modified stack frame

Fixes: a7ee22ee14 ("crypto: x86/sm4 - add AES-NI/AVX/x86_64 implementation")
