    resize2fs: don't attempt to calculate minimum size on fs with errors
    
    My old patch:
    
    	resize2fs: don't print minimum size if fs is not clean
    
    almost did this, but it still calculated the size; it just didn't print
    it.  Which is a bit silly.
    
    Jes had a pretty badly corrupted image which made the minimum size
    calculation go off into the weeds.  It was corrupted, and also marked
    as having an error.
    
    We'll eventually bail out for an unmounted filesystem if it's marked
    as being in an error state anyway; just move that test & bail-out
    to a much earlier point, and remove the now-duplicate one under the
    print_min_size block.
    
    This will catch & block all resize operations on an offline filesystem
    with errors, in one central place.
