percpu: reorganize chunk creation and destruction
Reorganize alloc/free_pcpu_chunk() such that chunk struct alloc/free
live in pcpu_alloc/free_chunk() and the rest in
pcpu_create/destroy_chunk(). While at it, add missing error handling
for chunk->map allocation failure.
This is to allow alternate chunk management implementation for percpu
nommu support.
