Btrfs: fix ctime update of on-disk inode
To reproduce the bug:
# touch /mnt/tmp
# stat /mnt/tmp | grep Change
Change: 2011-12-09 09:32:23.412105981 +0800
# chattr +i /mnt/tmp
# stat /mnt/tmp | grep Change
Change: 2011-12-09 09:32:43.198105295 +0800
# umount /mnt
# mount /dev/loop1 /mnt
# stat /mnt/tmp | grep Change
Change: 2011-12-09 09:32:23.412105981 +0800
We should update ctime of in-memory inode before calling
btrfs_update_inode().
