[Mesa-dev] [PATCH] i965: Fix leak in blorp CopyTexSubImage2D

[christopher.halse.rogers at canonical.com]

From: Christopher James Halse Rogers <raof at ubuntu.com>

_mesa_delete_renderbuffer does not call the driver-specific
renderbuffer delete function, so the blorp code was leaking the
Intel-specific bits, including some GEM objects.

Call the renderbuffer's ->Delete() method instead, which does the
right thing.

Fixes Unity rapidly sending the machine into the arms of the OOM-killer
