s390/kprobes: define insn cache ops within private header file
clang warns about an unused insn cache ops function:
arch/s390/kernel/kprobes.c:34:1:
error: unused function 'is_kprobe_s390_insn_slot' [-Werror,-Wunused-function]
DEFINE_INSN_CACHE_OPS(s390_insn);
^
./include/linux/kprobes.h:335:20: note: expanded from macro 'DEFINE_INSN_CACHE_OPS'
static inline bool is_kprobe_##__name##_slot(unsigned long addr) \
^
<scratch space>:88:1: note: expanded from here
is_kprobe_s390_insn_slot
^
Move the definition to a private header file, which is also similar to
the generic insn cache ops.
