kernel: audit: beautify code, for extern function, better to check its parameters by itself

  __audit_socketcall is an extern function.
  better to check its parameters by itself.

    also can return error code, when fail (find invalid parameters).
    also use macro instead of real hard code number
    also give related comments for it.
