[ Upstream commit 278e096063f1914fccfc77a617be9fc8dbb31b0e ] A test case revealed a race condition of an i/o completing on a thread parallel to the delete_association generating the aborts for the outstanding ios on the controller. The i/o completion was freeing the target fcloop context, thus the abort task referenced the just-freed memory. Correct by clearing the target/initiator cross pointers in the io completion and abort tasks before calling the callbacks. On aborts that detect already finished io's, ensure the complete context is called.
