iwlwifi: disable powersave for 4965
There's a bug in 4965 powersave that appears to be related to the way it keeps track of its data during sleep, but we haven't found it yet. Due to that, using powersave may spontaneously cause the device to SYSASSERT when transitioning from sleep to wake. Therefore, disable powersave for 4965, until (if ever, unfortunately) we can identify and fix the problem. Cf. http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1982 which was closed, but now has re-appeared with IDLE mode, which probably means we never really fixed it.
