Address the issue of reusing the same maple state for multiple
preallocations calls caused by MA_STATE_PREALLOC, and add a test for
this use case.

Included is a change to the testing code to reduce false positives in
the rcu race testing on faster machines.

I split this series into

- a standalone fix for 6.16-rcX and -stable.

- two standalone selftests patches for 6.17-rc1.

Is that OK?
