Commit 1dc92851 ("bpf: kernel side support for BTF Var and DataSec") added invocations of btf_type_is_resolve_source_only before btf_type_nosize_or_null which checks for the NULL pointer. Swap the order of btf_type_nosize_or_null and btf_type_is_resolve_source_only to make sure the do the NULL pointer check first.
