s390/cio: simplify css_generate_pgid
Simplify the css_generate_pgid code by using stap() independent of CONFIG_SMP. For !CONFIG_SMP builds stap() will deliver the address of the cpu we IPL'ed from (which can be != 0). Note: the ifdef was likely added to be compatible with _very_ old machines which we don't support anyway.
