Temp fix for broken multicast presence after WiFi/Ethernet merge.

This is a temporary fix.
The multicast notifications from server side need remote endpoint to be
null in caipadapter.c::CAIPSendDataThread().
But the function signature called from the RI layer into the CA layer
to send responses takes a CARemoteEndpoint struct which cannot be null.

The temp fix is to make caipclient.c think that a response is multicast if
the remoteAddress is the fixed multicast ip 224.0.1.187.
