f2fs: do not activate auto_recovery for fallocated i_size
commit 26787236b36660baf4d136281d40b5bb33a570ec upstream.
If a file needs to keep its i_size by fallocate, we need to turn off auto
recovery during roll-forward recovery.
This will resolve the below scenario.
1. xfs_io -f /mnt/f2fs/file -c "pwrite 0 4096" -c "fsync"
2. xfs_io -f /mnt/f2fs/file -c "falloc -k 4096 4096" -c "fsync"
3. md5sum /mnt/f2fs/file;
4. godown /mnt/f2fs/
5. umount /mnt/f2fs/
6. mount -t f2fs /dev/sdx /mnt/f2fs
7. md5sum /mnt/f2fs/file
