Btrfs: avoid orphan inode caused by log replay
drop_one_dir_item does not properly update inode's link count. It can be
reproduced by executing following commands:
#touch test
#sync
#rm -f test
#dd if=/dev/zero bs=4k count=1 of=test conv=fsync
#echo b > /proc/sysrq-trigger
This fixes it by adding an BTRFS_ORPHAN_ITEM_KEY for the inode
