Jason Gunthorpe 1baf6c5f7c iommufd: Add iopt_area_alloc() ...

[ Upstream commit 361d744ddd ]

We never initialize the two interval tree nodes, and zero fill is not the
same as RB_CLEAR_NODE. This can hide issues where we missed adding the
area to the trees. Factor out the allocation and clear the two nodes.
