The helper macro that records an error in BPF programs that exercise sock fields access has been inadvertently broken by adaptation work that happened in commit b18c1f0aa477 ("bpf: selftest: Adapt sock_fields test to use skel and global variables"). BPF_NOEXIST flag cannot be used to update BPF_MAP_TYPE_ARRAY. The operation always fails with -EEXIST, which in turn means the error never gets recorded, and the checks for errors always pass. Revert the change in update flags.
