iommu/amd: Split irq_lookup_table out of the amd_iommu_devtable_lock
The function get_irq_table() reads/writes irq_lookup_table while holding
the amd_iommu_devtable_lock. It also modifies
amd_iommu_dev_table[].data[2].
set_dte_entry() is using amd_iommu_dev_table[].data[0|1] (under the
domain->lock) so it should be okay. The access to the iommu is
serialized with its own (iommu's) lock.
So split out get_irq_table() out of amd_iommu_devtable_lock's lock.
