Some changes to the userspace selftest framework cause the iommufd tests
to start failing. This turned out to be bugs in the iommufd side that were
just getting uncovered.
- Deal with MAP_HUGETLB mmaping more than requested even when in MAP_FIXED
mode
- Fixup missing error flow cleanup in the test
- Check that the memory allocations suceeded
- Suppress some bogus gcc 'may be used uninitialized' warnings
