s390/entry: Save lowcore on invalid kernel stack
In case of an invalid kernel stack copy the current CPU's lowcore to
stack_invalid_lowcore, so it is available to debug tools after a crash.
The copy is helpful since the lowcore is modified e.g., when printing
messages before a dump is taken. Keep it as unmodified as possible and
as close to the event that caused register corruption.
