+++ This bug was initially created as a clone of Bug #1132469 +++

Description of problem:

When an inode's type is mismatching across the subvolumes of AFR, operations on it must not succeed and must fail with EIO.

Version-Release number of selected component (if applicable):
AFR-V2

How reproducible:
Always

Steps to Reproduce:
1. Create, start and mount a replicate volume.
2. 'mkdir foo' on the mountpoint.
3. Go to one of the bricks, do 'rm -rf foo', and perform 'touch foo'.
4. Perform 'ls -lR' on the mount point. Observe file type.

Actual results:

No error is reported on the mountpoint.
The inode is listed as a regular file.
But a stat on foo reports that foo is a directory.
echo 123 > /mnt/foo fails with EISDIR.
mkdir foo/bar succeeds.
From this point on, foo is listed as directory on doing ls -l.
foo continues to be a regular file on the brick where step 3 was performed.

Expected results:
Operations on such an inode where the replicas are not in agreement with respect to its type, must fail with EIO.

Additional info:
The test returns EIO (as expected) on AFR-V1.
