ext2fs_block_iterate2: Reflect errors from ext2fs_extent_set_bmap to caller

If the callback function tries to change a block, and
ext2fs_extent_set_bmap() fails for some reason (for example, there
isn't enough disk space to split a node and expand the extent tree,
make sure that error is reflected back up to the caller.
