Branch b1_6

Description: e2fsck reports "invalid unused inodes count"
Details    : If a new ldiskfs filesystem is created with the "uninit_groups"
	     feature and only a single inode is created in a group then the
	     "bg_unused_inodes" count is incorrectly updated.  Creating a
	     second inode in that group would update it correctly.
