There is a reversed if statement in amdgpu_preempt_mgr_new() so it
always returns -ENOMEM.

Fixes: 09b020bb05a5 ("Merge tag 'drm-misc-next-2021-06-09' of
git://anongit.freedesktop.org/drm/drm-misc into drm-next")
Signed-off-by: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
Most be some fallout from merging it with the TTM changes.

Anyway, patch is Reviewed-by: Christian König <christian.koenig@xxxxxxx>
This is obviously not for amd-staging-drm-next. Christian, are you going
to apply it to the relevant branches?
I've applied it to my drm-next branch.

I already pushed it to drm-misc-next last week.
