st/dri: no need to request fake front buffer, only handle it being returned
The previous behaviour was incorrect, and resulted in EXT_tfp being broken for DDX drivers that implement the correct behaviour (intel/radeon/nouveau). In the cases where a fake front buffer is required, the X server will return one when requesting __DRI_BUFFER_FRONT_LEFT. The Xorg state tracker (aka modesetting_drv) is likely broken now until it's modified to match the other drivers. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
