perf map: Fix error return code in maps__clone()
Although 'err' has been initialized to -ENOMEM, but it will be reassigned
by the "err = unwind__prepare_access(...)" statement in the for loop. So
that, the value of 'err' is unknown when map__clone() failed.
Fixes: 6c502584438bda63 ("perf unwind: Call unwind__prepare_access for forked thread")
