From: Ben Widawsky <benjamin.widawsky@xxxxxxxxx>
The bound list is global (all objects which back the VMAs are stored
here). Recently the BUG() in the offset lookup was demoted to a WARN,
but the fault actually lies in the caller, here.
This bug has existed since the initial introduction of PPGTT (however,
it was fixed in unmerged patches to fix up the error state).
