Steven Rostedt (VMware) b30a779d5c tracing: Initialize upper and lower vars in pid_list_refill_irq() ...

The upper and lower variables are set as link lists to add into the sparse
array. If they are NULL, after the needed allocations are done, then there
is nothing to add. But they need to be initialized to NULL for this to
work.
