ext4: clean up inode bitmaps manipulation in ext4_free_inode
- Reorganize locking scheme to batch two atomic operation in to one.
This also allow us to state what healthy group must obey following rule
ext4_free_inodes_count(sb, gdp) == ext4_count_free(inode_bitmap, NUM);
- Fix possible undefined pointer dereference.
- Even if group descriptor stats aren't accessible we have to update
inode bitmaps.
- Move non-group members update out of group_lock.
