Subject: [PATCH] ixgbe: fix registration order of driver and DCA nofitication

commit f01fc1a82c2ee68726b400fadb156bd623b5f2f1 upstream.

ixgbe_notify_dca cannot be called before driver registration
because it expects driver's klist_devices to be allocated and
initialized. While on it make sure debugfs files are removed
when registration fails.
