Define a QCA vendor attribute to update the listen interval

This commit defines an attribute
QCA_WLAN_VENDOR_ATTR_CONFIG_LISTEN_INTERVAL which allows the currently
used listen interval to be updated using
QCA_NL80211_VENDOR_SUBCMD_SET_WIFI_CONFIGURATION. This update applies
only during the association and is done without updating the AP about
the change.
