crimson/os/seastore/cache: clear extents_index when the booting is done

Since all extents including RetiredExtentPlaceholder are linked to lba
leaf nodes, Cache::extents_index is only useful to link all lba/backref
nodes and logical extents together before SeaStore is fully booted.

So we should clear Cache::extents_index after SeaStore is booted.
