s390/entry: Fix last breaking event handling in case of stack corruption
In case of stack corruption stack_invalid() is called and the expectation
is that register r10 contains the last breaking event address. This
dependency is quite subtle and broke a couple of years ago without that
anybody noticed.
Fix this by getting rid of the dependency and read the last breaking event
address from lowcore.
