It should be a less common case, but it is possible for a single bo to

So rather than completely fall over in this case, fallback to slow-path

libdrm_freedreno currently supports two backends, 'msm' for the upstream
drm/msm driver, and 'kgsl' which supports (to some extent), the android/
downstream kgsl driver plus a sort of drm shim nonsense to get flink
names.
However, kgsl support is strictly on a best-effort basis. Different
android devices with different versions of kgsl may have different
abi's. And the existing kgsl interface (at least the parts of it that
we use) is completely broken for 64bit. Lets disable it by default lest

There seem to be some cases (I've noticed this switching resolution in
some games, for example) where the fd can get closed() before the device
and all it's bo's are destroyed. Which, if the drm device is opened
again and bo's are allocated with the same handles, results that when
the first pipe_screen/pipe_context is destroyed causes the first dev to
close handles for bo's allocated by the second device.
The easy solution to that is to add a mode where the fd_device creates
it's own private fd (a dup()).
