ext4: make ext4_da_map_blocks() buffer_head unaware

Browse source

After calling the ext4_da_map_blocks(), a delalloc extent state could
be identified through the EXT4_MAP_DELAYED flag in map. So factor out
buffer_head related handles in ext4_da_map_blocks(), make this function
buffer_head unaware and becomes a common helper, and also update the
stale function commtents, preparing for the iomap da write path in the
future.
