rcutorture: Allow specifying per-scenario stat_interval

Browse source

The rcutorture test suite makes double use of the rcutorture.stat_interval
module parameter.  As its name suggests, it controls the frequency
of statistics printing, but it also controls the rcu_torture_writer()
stall timeout.  The current setting of 15 seconds works surprisingly well.
However, given that the RCU tasks stall-warning timeout is ten -minutes-,
15 seconds is too short for TASKS02, which runs a non-preemptible kernel
on a single CPU.

This commit therefore adds checks for per-scenario specification of the
rcutorture.stat_interval module parameter.
