Subject: ice: Check for actual link state of port after reset
Patch-mainline: v4.20-rc1
Git-commit: 5755143dd18d3b7fa97b419d18d9bb4764b7b46f
References: bsc#1118661 FATE#325277

We are currently replaying the link state of a port after a reset, but
it is possible that the link state of a port can change during the reset
process. So check for the current link state of a port during the rebuild
process of a reset.
