mm/arch: use __free_reserved_page() to simplify the code
Use __free_reserved_page() to simplify the code in arch.
It used split_page() in consistent_alloc()/__dma_alloc_coherent()/dma_alloc_coherent(),
so page->_count == 1, and we can free it safely.
__free_reserved_page()
ClearPageReserved()
init_page_count() // it won't change the value
__free_page()
