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.
