ext4: replace ext4_es_insert_extent() when caching on-disk extents

In ext4, the remaining places for inserting extents into the extent
status tree within ext4_ext_determine_insert_hole() and
ext4_map_query_blocks() directly cache on-disk extents. We can use
ext4_es_cache_extent() instead of ext4_es_insert_extent() in these
cases. This will help reduce unnecessary increases in extent sequence
numbers and cache invalidations after supporting IOMAP in the future.
