eCryptfs: Copy lower inode attrs before dentry instantiation
Copies the lower inode attributes to the upper inode before passing the
upper inode to d_instantiate(). This is important for
security_d_instantiate().
The problem was discovered by a user seeing SELinux denials like so:
type=AVC msg=audit(1236812817.898:47): avc: denied { 0x100000 } for
pid=3584 comm="httpd" name="testdir" dev=ecryptfs ino=943872
scontext=root:system_r:httpd_t:s0
tcontext=root:object_r:httpd_sys_content_t:s0 tclass=file
Notice target class is file while testdir is really a directory,
confusing the permission translation (0x100000) due to the wrong i_mode.
