rcu: Put panic_on_rcu_stall() after expedited RCU CPU stall warnings
When a normal RCU CPU stall warning is encountered with the panic_on_rcu_stall sysfs variable is set, the system panics only after the stall warning is printed. But when an expedited RCU CPU stall warning is encountered with the panic_on_rcu_stall sysfs variable is set, the system panics first, thus never printing the stall warning. This commit therefore brings the expedited stall warning into line with the normal stall warning by printing first and panicking afterwards.
