resize2fs: don't try to resize below calculated minimum 

Without a force flag, don't allow resize2fs to even start resizing
below what it thinks the minimum safe value is.

This may stop resizes which could otherwise proceed with a bit
of space still left, but seems like a reasonably safe thing to do.
