drm/i915: Only clear the GPU domains upon a successful finish
By clearing the GPU read domains before waiting upon the buffer, we run
the risk of the wait being interrupted and the domains prematurely
cleared. The next time we attempt to wait upon the buffer (after
userspace handles the signal), we believe that the buffer is idle and so
skip the wait.
There are a number of bugs across all generations which show signs of an
overly haste reuse of active buffers.
