    resize2fs: don't require fsck to print min size
    
    My previous change ended up requiring that the filesystem
    be fsck'd after the last mount, even if we are only querying
    the minimum size.  This is a bit draconian, and it burned
    the Fedora installer, which wants to calculate minimum size
    for every filesystem in the box at install time, which in turn
    requires a full fsck of every filesystem.
    
    Try this one more time, and separate out the tests to make things
    a bit more clear.  If we're only printing the min size, don't
    require the fsck, as this is a bit less dangerous/critical.
