target/tcm_fc: use CPU affinity for responses
commit 1ba0158fa66b5b2c597a748f87be1650c9960ccc upstream.
The libfc stack assigns exchange IDs based on the CPU the request
was received on, so we need to send the responses via the same CPU.
Otherwise the send logic gets confuses and responses will be delayed,
causing exchange timeouts on the initiator side.
