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.
