Subject: [PATCH 1/2] tools: Remove lockdep.h and its include from spinlock.h

Commit 58d6ea3085f2 ("xarray: Add XArray unconditional store
operations") adds this file at the same time that xarray and xarray
tests. However, xarray tests and other tools/ works with no problem
without this file.

The motivation for the deletion is that vhost tests/tools need to use
spinlock.h mock file, but at the moment it includes lockdep.h that is
only available under tools/testing/radix-tree.
