[PATCH AUTOSEL 5.15 08/65] drm/virtio: fix the missed drm_gem_object_put() in virtio_gpu_user_framebuffer_create()

[Sasha Levin]

From: Jing Xiangfeng <jingxiangfeng@xxxxxxxxxx>

[ Upstream commit a63f393dd7e1ebee707c9dee1d197fdc33d6486b ]

virtio_gpu_user_framebuffer_create() misses to call drm_gem_object_put()
in an error path. Add the missed function call to fix it.
