qcacmn: Add support to send max ndp sessions to fw

Firmware advertises max number of ndp sessions support in
wmi_service_ready_ext2 event. If the firmware advertised value of
max ndp sessions is non-zero, then host uses a minimum of max ndp
sessions of target_resource_config and firmware advertised max ndp
sessions to configure max ndp sessions in firmware using WMI_INIT_CMD.
