Subject: [PATCH] btrfs: Remove useless variable in write_ctree_super()

The function write_ctree_super() in disk-io.c uses variable ret to return
the result of function write_all_supers(). Since, this variable serves
no purpose, hence the patch removes it and returns the call of the
called function.
