btrfs: tree-checker: add missing returns after data_ref alignment checks

Browse Source 
commit 6d06b0ad94 upstream.

There are sectorsize alignment checks that are reported but then
check_extent_data_ref continues. This was not intended, wrong alignment
is not a minor problem and we should return with error.
