This happens in two cases:
- userspace got its fence accounting wrong or
- the kernel got its fence accounting wrong.
In both cases there's absolutely no point in calling evict_everything,
that will not magically bring back the missing fence. So return a
different (hopefully somewhat sensible) error code.
This has the added benefit that out-of-gtt can be distinguish from
broken fence accounting by simply looking at the ioctl return code.
