swapin_readahead: move and rearrange args
swapin_readahead has never sat well in mm/memory.c: move it to mm/swap_state.c beside its kindred read_swap_cache_async. Why were its args in a different order? rearrange them. And since it was always followed by a read_swap_cache_async of the target page, fold that in and return struct page*. Then CONFIG_SWAP=n no longer needs valid_swaphandles and read_swap_cache_async stubs.
