From: Luciano Coelho <[email protected]> If a monitor interface is added and then removed, we don't reset the mvm->ps_disabled flag, so we never re-enable power saving. Fix that and rearrange the code a bit.
Additionally, fix a small indentation mistake in the iwl_mvm_power_set_pm() function declaration.
