ext4: Fixed inode allocator to correctly track a flex_bg's used_dirs

Browse Source 
commit c4caae2518 upstream (as of v2.6.34-rc3)

When used_dirs was introduced for the flex_groups struct, it looks
like the accounting was not put into place properly, in some places
manipulating free_inodes rather than used_dirs.
