[PATCH 2/2] mm/memory-failure: use bool for forcekill state

[Ye Liu]

From: Ye Liu <liuye@xxxxxxxxxx>

'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.
