fscache emits a lot of duplicate cookie warnings with cifs because the
index key for the fscache cookies does not include everything that the
cifs_find_inode() function does. The latter is used with iget5_locked() to
distinguish between inodes in the local inode cache.
Fix this by adding the creation time and file type to the fscache cookie
key.
Additionally, add a couple of comments to note that if one is changed the
other must be also.
