    Cluster/DHT : Fixed crash due to null deref
    A lookup on a linkto file whose trusted.glusterfs.dht.linkto
    xattr points to a subvol that is not part of the volume
    can cause the brick process to segfault due to a null dereference.
    Modified to check for a non-null value before attempting to access
    the variable.
