drm/radeon: fix wait to actually occur after the signaling callback
A normal wait adds to the front of the tail. By doing something
similar to fence_default_wait the fence code can run without racing.
This is a complete fix for "panic on suspend from KDE with radeon",
and a partial fix for "Radeon: System pauses on TAHITI". On tahiti
si_irq_set needs to be fixed too, to completely flush the writes
before radeon_fence_activity is called in radeon_fence_enable_signaling.
