tools: fix userspace compilation with new test_xarray changes

Patch series "test_xarray: couple of fixes for v6-9-rc6", v2.

Here are a couple of fixes which should be merged into the queue for
v6.9-rc6.  The first one was reported by Liam, after fixing that I noticed
an issue with a test, and a fix for that is in the second patch.


This patch (of 2):

Liam reported that compiling the test_xarray on userspace was broken.  I
was not even aware that was possible but you can via and you can run these
tests in userspace with:

make -C tools/testing/radix-tree
./tools/testing/radix-tree/xarray

Add the two helpers we need to fix compilation.  We don't need a userspace
schedule() so just make it do nothing.
