xembedsniproxy: Fix high CPU usage when 0,0 is off-screen
Reverts 69786a1f, which is no longer needed after 50bbe56b
Initial workaround for Bug 357443 tries to detect and fix window stacking issues (for example after compositor restart). Unfortunately, it causes infinite loop when (0,0) position (were windows are originally positioned) is off-screen (this can happen in some less commonmulti-screen setups). Proper fix was added in !4324 (merged), so that faulty workaround is no longer needed.
