[PATCH][GIT PULL][v3.1] ftrace: Fix README to state tracing_on tostart/stop tracing

Ingo,

This patch isn't critical but it is rather embarrassing that
tracing_enabled has been marked deprecated, but we still report to use
it in the README file. This patch has extremely low risk in breaking
anything and fixes an embarrassing documentation issue.

I would like to see this fixed in the next major release.

Thanks!

ftrace: Fix README to state tracing_on to start/stop tracing

tracing_enabled option is deprecated.
To start/stop tracing, write to /sys/kernel/debug/tracing/tracing_on
without tracing_enabled. This patch is based on Linux 3.1.0-rc1
