[PATCH] tracing: Fix documentation about disabling options using trace_options

From: Srivatsa S. Bhat
Date: Mon Jan 28 2019 - 21:18:58 EST


From: Srivatsa S. Bhat (VMware) <srivatsa@xxxxxxxxxxxxx>

To disable a tracing option using the trace_options file, the option
name needs to be prefixed with 'no', and not suffixed, as the README
states. Fix it.
