MBSSID: Use DTIM Count 0 in the Beacon template for nontransmitted BSSID

Browse source 
The driver is expected to update the DTIM Count field for each BSS that
corresponds to a nontransmitted BSSID. Initialized this value to 0 in
the Beacon frame template so that the DTIM count would be somewhat
functional even if the driver were not to update this.
