[PATCH] drm/rockchip: cleanup fb when drm_gem_fb_afbc_init failed

[Andy Yan]

From: Andy Yan <andy....@rock-chips.com>

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.

Fixes: 7707f7227f09 ("drm/rockchip: Add support for afbc")
