The idea of printing objects used by each process is to judge how each
process is using them. This means that we need to evaluate whether the
object is bound for that particular process, rather than just whether it
is bound into the global GTT.
v2: Restore the non-full-ppgtt path for simplicity as we may not even
create vma with older hardware.
v3: Tweak handling of global entries and default context entries.
