sched/hmp: Fix memory leak when task fork fails
The scheduler allocates memory for the task load structures during
fork. It then relies to sched_exit() to be called to free that memory.
However, if the fork itself fails at any point after the allocation,
the memory is left unclaimed forever. Fix this memory leak by freeing
the allocated memory under error conditions.
