[dpdk-dev] [PATCH] eal: fix '--huge-unlink' option

[Pawel Wodkowski]

The final_va field is set during remap_segment() but this information is
not propagated to temporal copy of huge page memory configuration so the
unlink_hugepage_files() function wrongly assume that there is nothing to
unlink. Fix this issue by checking orig_va instead of final_va.

Fixes: 66cc45e293ed ("mem: replace memseg with memseg lists")
