The ->map_blocks interface returns a valid range for writeback, but we still call back into it for every block, which is a bit inefficient. Change iomap_writepage_map to use the valid range in the map until the end of the folio or the dirty range inside the folio instead of calling back into every block. Note that the range is not used over folio boundaries as we need to be able to check the mapping sequence count under the folio lock.
