zdb -L should skip leak detection altogether
Currently the point of -L option in zdb is to disable leak
tracing and the loading of space maps because they are expensive,
yet still do leak detection in terms of space. Unfortunately,
there is a scenario where this is a lie. If we are using zdb -L
on a pool where a vdev is being removed, zdb_claim_removing()
will open the metaslab space maps of that device.
This patch makes it so zdb -L skips leak detection altogether
and ensures that no space maps are loaded.
