[PATCH net 1/2] wireguard: noise: do not assign initiation time in if condition

[Jason A. Donenfeld]

From: Frank Werner-Krippendorf <m...@hb9fxq.ch>

Fixes an error condition reported by checkpatch.pl which caused by
assigning a variable in an if condition in wg_noise_handshake_consume_
initiation().
