[PATCH tip/core/rcu 1/2] rcutorture: Remove outdated config option description

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

From: SeongJae Park <sj38.park@gmail.com>

CONFIG_RCU_TORTURE_TEST_RUNNABLE has removed by commit 4e9a073f60367
("torture: Remove CONFIG_RCU_TORTURE_TEST_RUNNABLE, simplify code")
entirely but the document has not updated.  This commit updates the
document to remove the description for the config option and adding a
description for the alternative module parameter.

-It is also possible to specify CONFIG_RCU_TORTURE_TEST=y, which will
-result in the tests being loaded into the base kernel.  In this case,
-the CONFIG_RCU_TORTURE_TEST_RUNNABLE config option is used to specify
-whether the RCU torture tests are to be started immediately during
-boot or whether the /proc/sys/kernel/rcutorture_runnable file is used
-to enable them.  This /proc file can be used to repeatedly pause and
-restart the tests, regardless of the initial state specified by the
-CONFIG_RCU_TORTURE_TEST_RUNNABLE config option.

-You will normally -not- want to start the RCU torture tests during boot
-(and thus the default is CONFIG_RCU_TORTURE_TEST_RUNNABLE=n), but doing
-this can sometimes be useful in finding boot-time bugs.
