iwl3945: disable power save
commit bc45a67079c916a9bd0a95b0b879cc0f259bac6e upstream.
we see from http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2125
that power saving does not work well on 3945. Since then power saving has
also been connected with association problems where an AP deathenticates a
3945 after it is unable to transmit data to it - this happens when 3945
enters power savings mode.
Disable power save support until issues are resolved.
