When booting into a kexec kernel with intel_iommu=off, and
the previous kernel had intel_iommu=on, the IOMMU hardware
is still enabled and gets not disabled by the new kernel.
This causes the boot to fail because DMA is blocked by the
hardware. Disable the

In case of DMA_ATTR_FORCE_CONTIGUOUS allocations vm_area->pages
is invalid. __iommu_mmap_attrs and __iommu_get_sgtable cannot use
it. In first case temporary pages array is passed to iommu_dma_mmap,
in 2nd case single entry sg table is created directly instead
of calling helper.
