iwlwifi: add test to determine if interface in monitor mode 



mac80211 sets driver in monitor mode through configuring the
RX filters. We cannot trust priv->iw_mode to be accurate
regarding monitor mode as iw_mode is only set in add_interface,
which is not called by mac80211 when in monitor mode.
