mm/mm_init.c: simplify logic of deferred_[init|free]_pages
Function deferred_[init|free]_pages are only used in
deferred_init_maxorder(), which makes sure the range to init/free is
within MAX_ORDER_NR_PAGES size.
With this knowledge, we can simplify these two functions. Since
* only the first pfn could be IS_MAX_ORDER_ALIGNED()
Also since the range passed to deferred_[init|free]_pages is always from
memblock.memory for those we have already allocated memmap to cover,
pfn_valid() always return true. Then we can remove related check.
