mm: percpu: use kmemleak_ignore_phys() instead of kmemleak_free()
Kmemleak recently added a rbtree to store the objects allocted with
physical address. Those objects can't be freed with kmemleak_free().
According to the comments, percpu allocations are tracked by kmemleak
separately. Kmemleak_free() was used to avoid the unnecessary
tracking. If kmemleak_free() fails, those objects would be scanned by
kmemleak, which is unnecessary but shouldn't lead to other effects.
Use kmemleak_ignore_phys() instead of kmemleak_free() for those
objects.
