[PATCH] locktorture: Fix assignment of boolean variables

[Wen Yang]

Fix the following warnings reported by coccinelle:

kernel/locking/locktorture.c:703:6-10: WARNING: Assignment of bool to 0/1
kernel/locking/locktorture.c:918:2-20: WARNING: Assignment of bool to 0/1
kernel/locking/locktorture.c:949:3-20: WARNING: Assignment of bool to 0/1
kernel/locking/locktorture.c:682:2-19: WARNING: Assignment of bool to 0/1
kernel/locking/locktorture.c:688:2-19: WARNING: Assignment of bool to 0/1
kernel/locking/locktorture.c:648:2-20: WARNING: Assignment of bool to 0/1
kernel/locking/locktorture.c:654:2-20: WARNING: Assignment of bool to 0/1

This patch also makes the code more readable.
