ref_tracker: do xarray and workqueue job initializations earlier
The kernel test robot reported an oops that occurred when attempting to
deregister a dentry from the xarray during subsys_initcall().
The ref_tracker xarrays and workqueue job are being initialized in
late_initcall() which is too late. Move those to postcore_initcall()
instead.
Fixes: 65b584f53611 ("ref_tracker: automatically register a file in debugfs for a ref_tracker_dir")
Reported-by: kernel test robot <[email protected]>
