The test has become too big (>40 calls).
Split off dev_iommu_vfio and remove the overlap with dev_iommu_hwpt.

This should run without any errno returns. A number of problems have crept
in:
The kernel changed the size of the test ioctl from 0x38 to 0x48. The
generated description picked this up but the hardwired constant in the
test did not. Update all cases.
Fix TEST_OP_MOCK_DOMAIN to use the kernel changed ID layout and new
destruction sequence.
Move TEST_OP_MD_CHECK_* up into a region with a MOCK_DOMAIN and fix their
arguments so they work properly.
The test now passes on v6.8-rc3 with no error failures.

Add test program for ioctl$IOMMU_TEST_OP_MD_CHECK_MAP and
ioctl$IOMMU_TEST_OP_MD_CHECK_REFS to hit them quickly.
