[net-next 4/9] ice: Check for actual link state of port after reset

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Dave Ertman <david.m.ertman@intel.com>

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.
