[Glamor] [PATCH 3/3] uxa/glamor/dri: Should fixup the drawable pixmap.

[zhigang.gong at linux.intel.com]

From: Zhigang Gong <zhigang.gong at linux.intel.com>

Two fixes in this commit, first we only need to check the
front left buffer, for other attachment we don't need to
check them. The second is, we should fixup the pixmap's
drawable not the original drawable.
