ext4: don't use blocks freed but not yet committed in buddy cache init

Browse source

When we generate buddy cache (especially during resize) we need to
make sure we don't use the blocks freed but not yet comitted.  This
makes sure we have the right value of free blocks count in the group
info and also in the bitmap.  This also ensures the ordered mode
consistency
