Subject: [PATCH 1/2] drm: qxl: Remove dead qxl_io_flush_* functions

From: "Dr. David Alan Gilbert" <linux@...blig.org>

qxl_io_flush_release() and qxl_io_flush_surfaces() were both added
in 2013's
commit f64122c1f6ad ("drm: add new QXL driver. (v1.4)")

but have remained unused.  Remove them.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
