When filling in the middle of a previous delayed allocation, set br_startoff of the new delay extent to the right to NULLSTARTBLOCK so that it is ignored by xfs_bmap_extent_to_btree. This prevents a forced shutdown when that in-core extent is converted from delay to real and is found to be already in the btree. The value is overwritten below.
