patch__if different file type, then return error

//////////////////////////////////////////////////////////
Description of problem:
In spite of different file type,
 if file is same name and same inode number, then old inode cache is used.
This causes that you can not cd directory, can not cat SymbolicLink.
//////////////////////////////////////////////////////////

//////////////////////////////////////////////////////////
Version-Release number of selected component (if applicable):
CIFS client: kernel-3.18.0
samba server: samba-4.1.12-5.rc20
//////////////////////////////////////////////////////////

How reproducible:
Steps to Reproduce:

1. start smb at samba server

server# setenforce 0
server# vi /etc/samba/smb.conf
[share]
path = /home/share
public = yes
writable = yes

server# smbpasswd -a XXX(username)
server# systemctl restart smb

2. mount cifs at CIFS client

client# mount -o user=XXX,serverino //server/share /mnt/share

3. create and list file at CIFS client

client# cd /mnt/share
client# touch a; ls -li
total 0
2400376 -rw-r--r--. 1 root root 0 Dec 18 09:37 a

4. remove file and create Directory at samba server
   (Maybe you need repeat rm and mkdir 4 times
    until same inode number directory is made.)

server# rm -rf a; mkdir a; ls -li
total 0
2400376 drwxr-xr-x. 2 root root 0 Dec 18 09:38 a

5. list at CIFS client

client# ls -li
total 0
2400376 drwxr-xr-x. 2 root root 0 Dec 18 09:38 a
client# cd a
bash: cd: a: Not a directory

6. cannot remove DIR at CIFS client

client# rm -rf a
clinet$ ls -li
total 0
2400376 drwxr-xr-x. 2 root root 0 Dec 18 09:38 a

<<Fedora20 when SELinux is Enforcing, can not remove DIR>>
client# getenforce
Enforcing
client# rm -rf a
rm: cannot remove 'a': Permission denied
