cifs: Fix the target file was deleted when rename failed.
commit 9ffad9263b467efd8f8dc7ae1941a0a655a2bab2 upstream.
When xfstest generic/035, we found the target file was deleted
if the rename return -EACESS.
In cifs_rename2, we unlink the positive target dentry if rename
failed with EACESS or EEXIST, even if the target dentry is positived
before rename. Then the existing file was deleted.
We should just delete the target file which created during the
rename.
