[ Upstream commit 1b11063d32d7e11366e48be64215ff517ce32217 ]
The existing logic happens to work fine on UML, but is not correct when
running on other arches.
1. We didn't initialize `int err`, and kunit_filter_suites() doesn't
explicitly set it to 0 on success. So we had false "failures".
Note: it doesn't happen on UML, causing this to get overlooked.
2. If we error out, we do not call kunit_handle_shutdown().
This makes kunit.py timeout when using a non-UML arch, since the QEMU
process doesn't ever exit.
Fixes: a02353f49162 ("kunit: bail out of test filtering logic quicker if OOM")
