[PATCH v2 02/11] drm/qxl: more fence wait rework

[Gerd Hoffmann <kraxel@redhat.com>]

Move qxl_io_notify_oom() call into wait condition.
That way the driver will call it again if one call
wasn't enough.

Also allows to remove the extra dma_fence_is_signaled()
check and the goto.

Fixes: 5a838e5d5825 ("drm/qxl: simplify qxl_fence_wait")
