[PATCH net-next 3/6] ovpn: remove redundant peer NULL checks in crypto post functions

[Antonio Quartulli <antonio@openvpn.net>]

From: Marco Baffo <marco@mandelbit.com>

The AEAD helpers set the peer pointer in the skb control buffer before
any error return or crypto request submission. Both crypto paths hold
a peer reference until post-processing finishes.

Remove the redundant NULL checks before ovpn_peer_put() in
ovpn_encrypt_post() and ovpn_decrypt_post().
