Tetsuo Handa 4ca5ede07c hung_task: decrement sysctl_hung_task_warnings only if it is positive 
Since sysctl_hung_task_warnings == -1 is allowed (infinite warnings),
commit 48a6d64eda ("hung_task: allow hung_task_panic when
hung_task_warnings is 0") should decrement it only when it is not -1.

This prevents the kernel from ceasing warnings after the first
