ext4: fix fencepost in s_first_meta_bg validation

Oops, thanks for reporting the bug.  This fix should take care of your issue.

I was able to reproduce such a file system using:


export MKE2FS_FIRST_META_BG=2
mke2fs -t ext4 -b 4096 -N 90112 -I 128 -L DB -m 0 -O
dir_index,extent,filetype,flex_bg,^has_journal,large_file,^resize_inode,sparse_super,uninit_bg,meta_bg,^metadata_csum,^64bit
/tmp/test.img 8388608

I'm not sure how it got into that state, but I'm guess it involved online
resizing?
