[net-next 08/14] ice: silence some bogus error messages

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

From: Mitch Williams <mitch.a.williams@intel.com>

In some circumstances, VF devices can be deactivated while a message is
in-flight. In that case, a series of scary error message will be
printed in the log. Since these are actually harmless, check for this
case and suppress them. No harm, no foul.
