resize2fs: allow resizing flex_bg && !resize_inode file systems 

With the bug fixes from the last two commits, resize2fs can now fully
support off-line resizing of file systems with flex_bg even if the
resize_inode feature is not present; so we no longer need to disallow
this combination.

/*
* XXXX The combination of flex_bg and !resize_inode
* causes major problems for resize2fs, since when the
* group descriptors grow in size this can potentially
* require multiple inode tables to be moved aside to
* make room, and resize2fs chokes rather badly in
* this scenario. It's a rare combination, except
* when a filesystem is expanded more than a certain
* size, so for now, we'll just prohibit that
* combination. This is something we should fix
* eventually, though.
