GFS2: Remove localcaching mount option
This option defaulted to on for lock_nolock mounts and off otherwise. The only function was to avoid the revalidation of dentries. In the cluster case, that is entirely pointless and liable to cause coherency problems. The patch changes the revalidation to depend upon whether the fs is a local or cluster fs (i.e. it follows the existing default behaviour). I very much doubt anybody ever used this option as there is no reason to. Even so we will continue to accept it on the mount command line, but ignore it.
