xfs: use iomap for blocksize == PAGE_SIZE readpage and readpages
For file systems with a block size that equals the page size we never do
partial reads, so we can use the buffer_head-less iomap versions of
readpage and readpages without conflicting with the buffer_head structures
create later in write_begin.
