jffs2: remove unnecessary GC pass on sync

We do not need to call 'jffs2_write_super()' on sync. This function causes a GC pass to make sure the current contents is pushed out with the data which we already have on the media. But this is not needed on unmount and only slows sync down unnecessarily. It is enough to just sync the write-buffer. This call was added by one of the generic VFS rework patch-sets, see d579ed0.
