iwlwifi/iwl3945: fix suspend resume association bug
Patch fixes the following bugs at http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2005 http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2007 If we suspend with an association and then resumed, we need to synchronize the active rxon with staging rxon, else we will get an error when iwl_alive_start try to commit rxon and staging is set to channel 0. Before going to suspend staging and active rxon are in sync. After resuming from the suspend, iwl_mac_start is called and it clears the staging rxon. Patch fixes the bug by not clearing the staging rxon in iwl_mac_start. Patch also adds similar fix to 3945.
