Revert "drm/qxl: simplify qxl_fence_wait"

[ Upstream commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea ]

This reverts commit 5a838e5d5825c85556011478abde708251cc0776.

Changes from commit 5a838e5d5825 ("drm/qxl: simplify qxl_fence_wait") would
result in a '[TTM] Buffer eviction failed' exception whenever it reached a
timeout.
Due to a dependency to DMA_FENCE_WARN this also restores some code deleted
by commit d72277b6c37d ("dma-buf: nuke DMA_FENCE_TRACE macros v2").
