egl/dri2: set max values for pbuffer width and height

While these max values were previously fixed for pbuffer creation, this
change makes also eglGetConfigAttrib() return correct values.

Fixes following dEQP tests:

   dEQP-EGL.functional.create_surface.pbuffer.rgb888_no_depth_no_stencil
   dEQP-EGL.functional.create_surface.pbuffer.rgb888_depth_stencil
   dEQP-EGL.functional.create_surface.pbuffer.rgba8888_no_depth_no_stencil
   dEQP-EGL.functional.create_surface.pbuffer.rgba8888_depth_stencil
