x86, iommu: Fix IOMMU_INIT alignment rules
This boot crash was observed:
DMA-API: preallocated 32768 debug entries
DMA-API: debugging enabled by kernel config
BUG: unable to handle kernel paging request at 19da8955
IP: [<f4ffffff>] 0xf4ffffff
*pde = 00000000
The crux of the failure was that even if we did not use any
of the .iommu_table section, the linker would still insert it
in the vmlinux file. This patch fixes that and also fixes the
runtime crash where we would try to access the array.
