Fix ov292_020d4580 next-callback extern to canonical symbol name

The SetIndexedSlot next-callback reloc target 0x020d45bc is delinked
as the veneer symbol AllocatorFreeForExpHeap_0x020d45bc (a heuristic
NNS name), not func_ov292_020d45bc. getcand names relocs func_ovNN_ADDR
by default so the wrong name leaked into the .c; verify_idx masks
relocs so it passed byte-exact but the overlay link reported
"Undefined: func_ov292_020d45bc". Byte-identical after the rename.
