  iommufd/selftest: Fix build warnings due to uninitialized mfd (2025-06-24 15:45:13 -0300)

----------------------------------------------------------------
iommufd 6.16 first rc pull

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
