IB/ipoib: Do not warn if IPoIB debugfs doesn't exist
netdev_wait_allrefs() could rebroadcast NETDEV_UNREGISTER event multiple times until all refs are gone, which will result in calling ipoib_delete_debug_files multiple times and printing a warning. Remove the WARN_ONCE since checks of NULL pointers before calling debugfs_remove are not needed.
