[NPM][Inliner] Temporarily remove inline_stats test case for always
inline

The stats are printed at InlinePass destruction. When we have 2 of them,
it appears the destruction order of the Passes std::vector of the pass
manager differs in msan builds - example:
http://lab.llvm.org:8011/#/builders/74/builds/2135.

This reproes locally, too.

Temporarily removing the sub-test case, to green the build, and will
follow up with a stat dumping alternative that does not depend on vector
element dtor order.
