Zhen Lei c6f8714125 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: 6c50258443 ("perf unwind: Call unwind__prepare_access for forked thread")
