wifi: rtl8xxxu: Add sta_add() and sta_remove() callbacks

Browse Source 
In AP mode, sta_add() gets called when a new STA gets associated to
us. Call rtl8xxxu_refresh_rate_mask() to set a rate mask for the newly
connected STA (referenced by the macid) and then send a media connnect
report. Ignore the call to sta_add() in station mode.

Reserve one macid for broadcast/multicast packets in init.
