x86, cpufeature: Suppress compiler warning with gcc 3.x

Gcc 3.x generates a warning

  arch/x86/include/asm/cpufeature.h: In function `__static_cpu_has':
  arch/x86/include/asm/cpufeature.h:326: warning: asm operand 1 probably doesn't match constraints

on each file.
But static_cpu_has() for gcc 3.x does not need __static_cpu_has().
