nl80211: Use max associated STAs information in AP mode

Propagate max associated STAs in AP mode advertised by the driver to
core wpa_supplicant implemantion. This allows wpa_supplicant to update
the P2P GO group limit information automatically without having to
configure this limit manually. The information (if available) is also
used in the generic AP implementation to control maximum number of STA
entries.
