[RHEL-9.1.0 BZ 2068207] redhat: configs: Enable CONFIG_INTEL_IOMMU_DEBUGFS
Bugzilla: https://bugzilla.redhat.com/2068207
Testing: Booted debug kernel and verified intel iommu debugfs information is present.
Enable debugfs for Intel iommu in debug kernels to aid in debugging. This MR also contains a patch to clean up a kasan warning noticed when booting the debug kernel. As Kees notes in the commit in this case it is harmless, but cleaning it up to get rid of the warning.
