iommu: Simplify and fix ida handling

Browse source

Ida handling can be much simplified by using the ida_simple_.. functions.

This change also fixes the bug that previously checking for errors
returned by ida_get_new() was incomplete.
ida_get_new() can return errors other than EAGAIN, e.g. ENOSPC.
This case wasn't handled.
