documentation: Update sysfs path for rcu_cpu_stall_timeout

Commit 6bfc09e2327d ("rcu: Provide RCU CPU stall warnings for tiny RCU")
moved the rcu_cpu_stall_timeout module parameter from rcutree.c to
rcupdate.c, but failed to update Documentation/RCU/stallwarn.txt. This

rcu_cpu_stall_timeout.

         this parameter is checked only at the beginning of a cycle.
         So if you are 10 seconds into a 40-second stall, setting this
         sysfs parameter to (say) five will shorten the timeout for the
