    bsdinstall partedit: Apply changes from scripted installs
    
    I got a check inverted in a previous cleanup commit and as a result
    partedit was only applying GEOM changes (and generating an /etc/fstab)
    if it got an error reading the current GEOM mesh.  Instead, it needed
    to do those actions if it succeeded in reading the mesh.
    
    The lack of /etc/fstab meant that bsdinstall mount didn't mount
    anything in a scripted install.
