Bdevperf have returned immediately if -ENOMEM, continued if failure
due to other reasons, and registered the created target otherwise.
So, keep this behavior by passing the reference to the pointer to
struct io_target, and check both return code and the value of the
reference.
And this refactoring will clarify the logic related with target
assigment to cores.
