It is unclear to me that there is any utility in the following:

         rcu_read_unlock();
         rcu_read_lock();

So this patch removes the two instances of the above from ip_vs_conn.c.

This was introduced in 7cf2eb7bccbe0d7a8ab1d1382c4faa2b3abf817f ("ipvs: fix
sparse warnings for ip_vs_conn listing") as part of cleaning up warnings
flagged by sparse.

Compile and sparse tested only.
