linke li a10e3cbf32 rcutorture: Re-use value stored to ->rtort_pipe_count instead of re-reading
Currently, the rcu_torture_pipe_update_one() writes the value (i + 1)
to rp->rtort_pipe_count, then immediately re-reads it in order to compare
it to RCU_TORTURE_PIPE_LEN.  This re-read is pointless because no other
update to rp->rtort_pipe_count can occur at this point.  This commit
therefore instead re-uses the (i + 1) value stored in the comparison
instead of re-reading rp->rtort_pipe_count.
