resize2fs: relax requirements for -P output a bit

Requiring an immediate pre-fsck before printing a minimum resize size seems a bit draconian; if the fs isn't clean or marked with error, then certainly, but for an informational minimum size, I don't think we need to require a fsck since last mount.

I had simply copied the checks from the actual resize path, previously.

Installers use this option (-P) to gather minimum resize info, and requiring an actual fsck before use just seems to go too far.

Makes sense. I've added it to the e2fsprogs maint branch.
