ext4: make ext4_es_insert_delayed_block() return void
Now it never fails when inserting a delay extent, so the return value in
ext4_es_insert_delayed_block is no longer necessary, let it return void.
[ Fixed bug which caused system hangs during bigalloc test runs. See
https://lore.kernel.org/r/20230612030405.GH1436857@mit.edu for more
details. -- TYT ]
