Subject: [PATCH] ecryptfs: Fix refcnt leak on ecryptfs_follow_link() error
 path

If ->follow_link handler return the error, it should decrement
nd->path refcnt. But, ecryptfs_follow_link() doesn't decrement.

This patch fix it by using usual nd_set_link() style error handling,
instead of playing with nd->path.
