sched/walt: Fix the memory leak of idle task load pointers
The memory for task load pointers are allocated twice for each
idle thread except for the boot CPU. This happens during boot
from idle_threads_init()->idle_init() in the following 2 paths.
1. idle_init()->fork_idle()->copy_process()->
sched_fork()->init_new_task_load()
2. idle_init()->fork_idle()-> init_idle()->init_new_task_load()
The memory allocation for all tasks happens through the 1st path,
so use the same for idle tasks and kill the 2nd path. Since
the idle thread of boot CPU does not go through fork_idle(),
allocate the memory for it separately.
