NFSv4: Fix an oops in nfs4_fill_super
The mount statistics patches introduced a call to nfs_free_iostats that is not only redundant, but actually causes an oops. Also fix a memory leak due to the lack of a call to nfs_free_iostats on unmount. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
