iommu/amd: Hide unused iommu_table_lock



The newly introduced lock is only used when CONFIG_IRQ_REMAP is enabled:

drivers/iommu/amd_iommu.c:86:24: error: 'iommu_table_lock' defined but not used [-Werror=unused-variable]
 static DEFINE_SPINLOCK(iommu_table_lock);

This moves the definition next to the user, within the #ifdef protected
section of the file.

Fixes: ea6166f4 ("iommu/amd: Split irq_lookup_table out of the amd_iommu_devtable_lock")
