RFNoC: Re-enable flow ctrl for blocks on same xbar
Prior commit disabled flow control for all lossless links,
including links between blocks on the same crossbar. That
caused packets to jam up the crossbar leading to control
packets failing to ACK under certain conditions. This
reverts it so flow control is enabled and the crossbar is
kept clear.
