[egfx] reset total decoded frames when receiving caps

Browse Source 
It seems like some windows servers don't like to receive ack frame messages
with a totalDecodedFrame number that is bigger than the frameId.
That can happen if the connection starts, some frames are decoded, we receive a
renegotiate message, then egfx channel is reopened and the frame ids we receive
go back to 1. In the previous situation, we ended up with sending an ack
with frameId=1 and totalDecodedFrames=38, with the patch totalDecodedFrames is
reset when receiving caps, so it's always lower than frameId.
