User_data_available is just a signal that tells you that at least one word of data is buffered in the internal FIFO. Control_done tells you when all the reads have completed.
In your 000 state you have multiple drivers of the 'go' register. I'm kinda surprised that compiled to be honest. If 'read_count' was coded in such a way that it would never hit the value of 100000 then I can see why it was allowed to compile since the 'go' assertion would get optimized away. Are you reading multiple words of data from memory or just one at a time? If it is just one then I recommend building an Avalon read master instead since the master template is meant for reading buffers from memory.
