mm, hwpoison: fix possible use-after-free in mf_dax_kill_procs()
After kill_procs(), tk will be freed without being removed from the
to_kill list. In the next iteration, the freed list entry in the to_kill
list will be accessed, thus leading to use-after-free issue. Adding
list_del() in kill_procs() to fix the issue.
