The second patch, returns success on a reset of the buffer even if

I realized we should update the snapshot documentation together with
this change.
I attached a patch to update the documentation. Could you include this
patch?
Thanks,

Subject: [PATCH] tracing: update documentation of snapshot utility
Now, "snapshot" file returns success on a reset of snapshot buffer
even if the buffer wasn't allocated, instead of returning EINVAL.
This patch updates snapshot desctiption according to the change.
