refperf: Set reader_tasks to NULL after kfree() 



Set reader_tasks to NULL after kfree() in ref_scale_cleanup() to
improve debugging experience with kernel debugging tools. This
follows the common pattern of NULLing pointers after freeing to
avoid dangling pointer issues during debugging sessions.

Setting pointers to NULL after freeing helps debugging tools like
kdgb,drgn, and other kernel debuggers by providing clear indication
that the memory has been freed and the pointer is no longer valid.
