[PATCH] ext3: don't start a commit in write_super()

From: bzzz@tmi.comex.ru

Now we have sync_fs(), the kludge of using write_super() to detect when the
VFS is trying to sync the fs is unneeded.

With this change we don't accidentally run commits in response to kupdate
and bdflush activity and it speedup up some heavy workloads significantly.
