Alexey Romanov 4249a05ff6 zsmalloc: zs_destroy_pool: add size_class NULL check
Inside the zs_destroy_pool() function, there can still be NULL size_class
pointers: if when the next size_class is allocated, inside
zs_create_pool() function, kzalloc will return NULL and handling the error
condition, zs_create_pool() will call zs_destroy_pool().
