UPSTREAM: bpf: Fix returned error sign when link doesn't support updates

Browse source 
System calls encode returned errors as negative values. Fix a typo that
breaks this convention for bpf(LINK_UPDATE) when bpf_link doesn't support
update operation.

Fixes: f9d041271cf4 ("bpf: Refactor bpf_link update handling")
