Subject: ext4: let ext4 get free blocks count of uninit groups from desc

Hi all,

I do not know why ext4 does not get free blocks count of BLOCK_UNINIT groups
from group descriptors directly in the past.  But now, according to e2fsprogs
and code of kernel side we can get free blocks count from descriptors for
BLOCK_UNINIT groups, rather than compute it.  This can simplifies code a lot.
