l2tp: cleanup l2tp_tunnel_delete calls

Browse source 
l2tp_tunnel_delete does not return anything since commit 62b982eeb4
("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.
