intel-iommu: Remove superfluous iova_alloc_lock from IOVA code
We only ever obtain this lock immediately before the iova_rbtree_lock, and release it immediately after the iova_rbtree_lock. So ditch it and just use iova_rbtree_lock. [v2: Remove the lockdep bits this time too] Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
