====================
Two small fixes for global subprog tagging
Fix a bug with passing trusted PTR_TO_BTF_ID_OR_NULL register into global
subprog that expects `__arg_trusted __arg_nullable` arguments, which was
discovered when adopting production BPF application.
Also fix annoying warnings that are irrelevant for static subprogs, which are
just an artifact of using btf_prepare_func_args() for both static and global
subprogs.
