The debugfs_create_dir() function returns error pointers,
it never returns NULL. Most incorrect error checks were fixed,
but the one in bond_create_debugfs() was forgotten.

Fix the remaining error check.

	Seems fine to me; note that almost nobody uses this as bonding
debugfs is hidden behind !CONFIG_NET_NS.
