drm/rockchip: cleanup fb when drm_gem_fb_afbc_init failed

Browse Source 
[ 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.
