ext4: Avoid double dirtying of super block in ext4_put_super()
While reading code I noticed that ext4_put_super() dirties the superblock bh twice. It is always done in ext4_commit_super() too. Remove the redundant dirty operation. Should be a nop semantically. Signed-off-by: Andi Kleen <ak@linux.intel.com>
