From: Alaa Hleihel <alaa@xxxxxxxxxxxx>
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.
Fixes: 771a52584096 ("IB/IPoIB: ibX: failed to create mcg debug file")
