drm/msm/sde: set correct timeline at fence create

This change adds the offset to the associated timeline
when the retire and release fences are created.
The DRM client queries the fences using the atomic commit
instead of set_property ioctl. So the sync point should
contain the updated timeline before sending the FDs to
client.
