Nothing calls this function. Remove it.
With this, the last user of CONFIG_CIFS_EXPERIMENTAL has been
removed. Also, update the README.

- Enables cifs features under testing. These features are
- experimental and currently include DFS support and directory
- change notification ie fcntl(F_DNOTIFY), as well as the upcall
- mechanism which will be used for Kerberos session negotiation
- and uid remapping. Some of these features also may depend on
- setting a value of 1 to the pseudo-file /proc/fs/cifs/Experimental
- (which is disabled by default). See the file fs/cifs/README
- for more details. If unsure, say N.

Per share (per client mount) statistics are available in /proc/fs/cifs/Stats

represent the number of successful (ie non-zero return code from the server)
