btrfs: raid56: fix an incorrect csum skip during scrub

Commit 7425a2894019 ("btrfs: introduce btrfs_bio_for_each_block_all()
helper") uses the new helper to replace the nested loop inside
verify_bio_data_sectors(), which simplifies the code.

However that also changed the behavior of "continue" when a block has no
data checksum.

Previously the "continue" would skip the old for() loop, which would also
increase @total_sector_nr.

Now the "continue" will skip the new btrfs_bio_for_each_block_all()
loop, which doesn't update @total_sector_nr.

This means if we hit a block that has no data checksum, we will skip all
the remaining blocks no matter if they have data checksum.
As @total_sector_nr will never be updated, and that test_bit() will
always return false.

Fix it by increasing @total_sector_nr before calling "continue".
