btrfs: print-tree: parent bytenr must be aligned to sector size
commit c87f318e6f47696b4040b58f460d5c17ea0280e6 upstream.
Check nodesize to sectorsize in alignment check in print_extent_item.
The comment states that and this is correct, similar check is done
elsewhere in the functions.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: ea57788eb76d ("btrfs: require only sector size alignment for parent eb bytenr")
