This header is private data and we shouldn't (and aren't) using it in
the tracing_sysview.h. SystemView tracing works fine without it, as
tested with the philosophers sample.
This commit fixes the build when bluetooth SMP and SystemView tracing
are used, because the kernel_structs.h inclusion ends up pulling in
kernel_internal.h, which declares smp_init(), whose declaration
conflicts with another internal routine by the same name in
subsys/bluetooth/host/smp.c.
