drm/nouveau/drm/noveau: fix reference count leak in nouveau_fbcon_open
nouveau_fbcon_open() calls calls pm_runtime_get_sync() that increments the reference count. In case of failure, decrement the ref count before returning the error. Signed-off-by: Aditya Pakki <pakki001@umn.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
