xfs: handle "raw" delayed extents xfs_reflink_trim_around_shared
Delalloc extents in the extent list contain the number of reserved
indirect blocks in their startblock value and don't use the magic
DELAYSTARTBLOCK constant. Ensure that xfs_reflink_trim_around_shared
handles them properly by checking for isnullstartblock().
