Subject: [PATCH] net/i40e: fix link status update

[ upstream commit b5f6272c242f12fa3403b0d7e9da18fb83da17d4 ]

Link status is not updated correctly, link speed is 0
when link is up and link speed is not 0 when link is
down. This patch fixes the issue.

Fixes: eef2daf2e199 ("net/i40e: fix link update no wait")
