mm/madvise: add MF_ACTION_REQUIRED to madvise(MADV_HWPOISON)
The soft hwpoison injector via madvise(MADV_HWPOISON) operates in a
synchrous way in a sense, the injector is also a process under test, and
should it have the poisoned page mapped in its address space, it should
legitimately get killed as much as in a real UE situation.
