bpf: make sure scalar args don't accept __arg_nonnull tag
Move scalar arg processing in btf_prepare_func_args() after all pointer
arg processing is done. This makes it easier to do validation. One
example of unintended behavior right now is ability to specify
__arg_nonnull for integer/enum arguments. This patch fixes this.
