util: Make some iova_tree parameters const
As qemu guidelines: Unless a pointer is used to modify the pointed-to storage, give it the "const" attribute. In the particular case of iova_tree_find it allows to enforce what is requested by its comment, since the compiler would shout in case of modifying or freeing the const-qualified returned pointer.
