net: dsa: Bring back device detaching in dsa_slave_suspend()

[ Upstream commit f154be24 ]

Commit 448b4482 ("net: dsa: Add lockdep class to tx queues to avoid
lockdep splat") removed the netif_device_detach() call done in
dsa_slave_suspend() which is necessary, and paired with a corresponding
netif_device_attach(), bring it back.
