cortex_m: tz_ns.h: Fix compiling with arm-clang

We get the following error when building with arm-clang:

error: non-ASM statement in naked function is not supported
        __TZ_WRAP_FUNC(preface, foo1, postface);
        ^
tests/arch/arm/arm_tz_wrap_func/src/main.c:69:25: note: attribute is here
uint32_t __attribute__((naked)) wrap_foo1(uint32_t arg1, uint32_t arg2,
                        ^
1 error generated.

Remove the do/while wrapper to make this a true naked function.
