drm: Fix object leak in DRM_IOCTL_GEM_CHANGE_HANDLE

Browse source

commit 630efee949 upstream.

Add missing drm_gem_object_put() call when drm_gem_object_lookup()
successfully returns an object. This fixes a GEM object reference
leak that can prevent driver modules from unloading when using
prime buffers.

Fixes: 53096728b8 ("drm: Add DRM prime interface to reassign GEM handle")
