mac80211: improve RX aggregation data in debugfs
When the driver sets the SUPPORTS_REORDERING_BUFFER hardware flag, the debugfs data for RX aggregation sessions won't even indicate that a session is open. Since the previous fix to store the dialog token separately, we can indicate that it's open and add the token so that there's at least some data (ssn is not available.)
