Subject: [PATCH 5.12 617/677] nfp: devlink: initialize the devlink port attribute "lanes"

From: Yinjun Zhang <yinjun.zhang@...igine.com>

[ Upstream commit 90b669d65d99a3ee6965275269967cdee4da106e ]

The number of lanes of devlink port should be correctly initialized
when registering the port, so that the input check when running
"devlink port split <port> count <N>" can pass.

Fixes: a21cf0a8330b ("devlink: Add a new devlink port lanes attribute and pass to netlink")
