mm/memory-failure: use bool for forcekill state

'forcekill' is used as a boolean flag to control whether processes should
be forcibly killed.  It is only assigned from boolean expressions and
never used in arithmetic or bitmask operations.

Convert it from int to bool.

No functional change intended.
