i965: Move control flush into pipelined conditional render
The nv_conditional_render piglits were sporadically failing. Moving
the control flush from the write and placing it just before the read
was sufficient to make the piglits pass a 1000/1000 times. The bspec
says that the flush enable bit "waits until all previous writes of
immediate data from post sync circles are complete before executing the
next command" - the operative word being previous!
