x86/entry_32: Convert X86_INVD_BUG to ALTERNATIVE macro

Booting a 486 kernel on an AMD guest with this patch applied, says:

  apply_alternatives: feat: 0*32+25, old: (c160a475, len: 5), repl: (c19557d4, len: 5)
  c160a475: alt_insn: 68 10 35 00 c1
  c19557d4: rpl_insn: 68 80 39 00 c1

which is:

  old insn VA: 0xc160a475, CPU feat: X86_FEATURE_XMM, size: 5
  simd_coprocessor_error:
           c160a475:      68 10 35 00 c1          push $0xc1003510 <do_general_protection>
  repl insn: 0xc19557d4, size: 5
           c160a475:      68 80 39 00 c1          push $0xc1003980 <do_simd_coprocessor_error>
