Subject: [PATCH 5/8] doc: Remove kernel-parameters.txt entry for rcutorture.read_exit

From: "Paul E. McKenney" <paulmck@...nel.org>

There is only ever the one read-exit task, and there is no module
parameter named rcutorture.read_exit, so remove the bogus documentation.
Instead, use rcutorture.read_exit_burst to enable/disable read-exit
race testing.
