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: ea6166f4b83e ("iommu/amd: Split irq_lookup_table out of the amd_iommu_devtable_lock")
