[RFC 26/29] dma-buf/fence: remove pointless fence_timeline_signal at destroy phase

[Gustavo Padovan]

From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>

All changes to timeline value come through the user via
fence_timeline_signal() calls. When fence_timeline_destroy() is called no
changes on timeline->value happens hence call fence_timeline_signal() with
no increment is pointless.
