[dev.link] cmd/link: fix data race on AIX

On AIX, in relocsym we call Xcoffadddynrel, which adds a
relocation record to a global array. relocsym already runs in
parallel. In the past we only parallelize over segments, and
we call Xcoffadddynrel only for symbols in data segment, so it is
effectively called sequentially. In CL 239197 we started to do
more fine-grained parallelism, so we need to make sure it is safe
to call Xcoffadddynrel in parallel.

Fix AIX build.
