[PATCH 07/10] btrfs: fix wrong ctime when adding link

[Miao Xie <miaox@cn.fujitsu.com>]

the ctime of file has not been updated when I create a link for it.

Steps to reproduce:
 # touch file1
 # stat -c %Z file1
 1273592239
 # link flink1 file1
 # stat -c %Z file1
 1273592239             <-- have not been updated

This patch fix this problem.
