mm: vmalloc: use trace_purge_vmap_area_lazy event

This is for debug purposes and is called when all outstanding areas are
removed back to the vmap space.  It gives some extra information about:

- a start:end range where set of vmap ares were freed;
- a number of purged areas which were backed off.
