l2tp: cleanup l2tp_tunnel_delete calls

[ Upstream commit 4dc12ffeaeac939097a3f55c881d3dc3523dff0c ]

l2tp_tunnel_delete does not return anything since commit 62b982eeb458
("l2tp: fix race condition in l2tp_tunnel_delete").  But call sites of
l2tp_tunnel_delete still do casts to void to avoid unused return value
warnings.

Kill these now useless casts.
