    Fix device name and mount point in utils
    
    This patch fixes a regression introduced by commit 04f7da3 whereby
    the gfs2-utils identified whether a gfs2 file system was mounted.
    The method works fine when specifying the mount point for tools like
    gfs2_grow.  However, it doesn't work when the device is specified.
    The solution is to copy the discovered device name and mount point
    into the proper libgfs2 variables used by the utils.
