This patch makes sure the value of max_num_peers matches num_peers in hw_params (if set to a non zero value). hw_params->num_peers is used in the TLV WMI init command. If ar->max_num_peers is not set to the same value, there is a risk that the user creates more peers than the maximum number of peers supported by the device.
