Subject: [PATCH] net/ixgbe: fix busy wait during checking link status
If we haven't set wait_to_complete, there is no need to busy wait
until we have a link status. Applications, like bonding, use the
wait_to_complete flag to indicate that they will be doing their own
busy wait and will likely be polling again shortly.
Fixes: dc66e5fd01b9 ("net/ixgbe: improve link state check on VF")
