[PATCH 2/2] radeon: Only destroy fbdev framebuffer if it was initialized

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

Fixes crash when trying to unload the amdgpu module before the fbdev
framebuffer was initialized, which can happen since the DRM fbdev helper
code supports deferred setup.
