Amery HungandEduard Zingerman 289e680c89 bpf: Reject passing scalar NULL to nonnull arg of a global subprog ...

A global subprogram argument tagged __arg_nonnull is set up as a
non-nullable PTR_TO_MEM. However the verifier does not check against a
scalar NULL, leading to real NULL pointer dereference. Reject it as
well.

Fixes: 94e1c70a34 ("bpf: support 'arg:xxx' btf_decl_tag-based hints for global subprog args")
