scftorture: Fix distribution of short handler delays
The scftorture test module's scf_handler() function is supposed to provide three different distributions of short delays (including "no delay") and one distribution of long delays, if specified by the scftorture.longwait module parameter. However, the second of the two non-zero-wait short delays is disabled due to the first such delay's "goto out" not being enclosed in the "then" clause with the "udelay()". This commit therefore adjusts the code to provide the intended set of delays. Fixes: e9d338a0b179 ("scftorture: Add smp_call_function() torture test") Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
