[ Upstream commit 099593a28138b48feea5be8ce700e5bc4565e31d ]
In the function drm_gem_fb_init_with_funcs, the framebuffer (fb) and its corresponding object ID have already been registered.
So we need to cleanup the drm framebuffer if the subsequent execution of drm_gem_fb_afbc_init fails.
Directly call drm_framebuffer_put to ensure that all fb related resources are cleanup.
