It has been observed that the wireless interface ocassionally fails to resume
from suspend on extensive long run validation testing, so we workaround it by
bringing the interface down before suspend and bring it up again after resume
This reverts commit a77cd1406d.

The suspend script did a ifup/ifdown on wlan0 to workaround issues we
had using wireless drivers on some platforms.
