mm/kmemleak: use PF_KTHREAD flag to detect kernel threads
Replace the current->mm check with PF_KTHREAD flag for more reliable
kernel thread detection in scan_should_stop(). The PF_KTHREAD flag is the
standard way to identify kernel threads and is not affected by temporary
mm borrowing via kthread_use_mm() (although kmemleak does not currently
encounter such cases, this makes the code more robust).
No functional change.
