[PATCH v2 2/2] target/s390x: Use s390_skeys_get|set() helper

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Commit c9274b6bf0 ("target/s390x: start moving TCG-only code
to tcg/") moved mem_helper.c, but the trace-events file is
still in the parent directory, so is the generated trace.h.

Call the s390_skeys_get|set() helper, removing the need
for the trace event shared with the tcg/ sub-directory
