perf maps: Fix fixup_overlap_and_insert that can break sorted by name order

[ Upstream commit c4f3ff3 ]

When an entry in the address array is replaced, the corresponding name
entry is replaced. The entries names may sort differently and so it is
important that the sorted by name property be cleared on the maps.
