[Glamor] [PATCH 2/2] Release previous textre/fb when bind a new texture to a pixmap.

[zhigang.gong at linux.intel.com]

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

As we want to support DRI2 drawable which may create a new textured_drm
to a pre-existing texture_only pixmap, we have to add this logical.
