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.
