ext3: Replace lock/unlock_super() with an explicit lock for resizing
Use a separate lock to protect s_groups_count and the other block
group descriptors which get changed via an on-line resize operation,
so we can stop overloading the use of lock_super().
Port of ext4 commit 32ed5058ce90024efcd811254b4b1de0468099df by
Theodore Ts'o <tytso@mit.edu>.
