sched: hmp: Fix potential task_struct memory leak

We use get_task_struct to increment the ref count on a task_struct
so that even if the task dies with a pending migration we are still
able to read the memory without causing a fault.

In the case of non-running tasks, we forgot to decrement the ref
count when we are done with the task.
