btrfs-progs: corrupt-block: Change format of -d option

Currently if we want to delete an item we need to invoke corrupt block
like so:

  btrfs-corrupt-block [-r <numeric id of root>] -K <objectid,type,offset> -d

Instead, this patch converts the format to:

  btrfs-corrupt-block [-r <numeric id of root>] -d <objectid,type,offset>
