[RFC patch 09/41] s390/stacktrace: Remove the pointless ULONG_MAX marker

[Thomas Gleixner]

Terminating the last trace entry with ULONG_MAX is a completely pointless
exercise and none of the consumers can rely on it because it's
inconsistently implemented across architectures. In fact quite some of the
callers remove the entry and adjust stack_trace.nr_entries afterwards.
