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

[ upstream commit 0046ba5c27bd50edc695a6760355915b89bc60e0 ]

Fix the redundant delay in function link update. There is no need to
call rte_delay_ms and hold CPU for 100ms when link status is up.

Fixes: 263333bbb7a9 ("i40e: fix link status timeout")
