[PATCH] radeon/glamor: with new pixmap for dri2 drawable no need to create new texture

[j.glisse at gmail.com]

From: Jerome Glisse <jglisse at redhat.com>

When creating a new pixmap/bo for dri2 drawable there is no need to create a
new texture, instead the texture associated with the new pixmap should be use
otherwise there is a missmatch between the bo backing the texture for the
drawable and the bo used by dri2 client.
