iwlagn: 5000 do not support idle mode
5000 series has issue supporting power save idle mode:
commit 9dc2153315
iwlwifi: always support idle mode for agn devices
For agn devices, always support idle mode which help power
consumption in idle unassociated state.
the above changes cause 5000 become not stable when power management is "on"
