Clear trace_state data structure when starting trace in __synth_event_trace_start() internal function. Currently trace_state is initialized only in the synth_event_trace_start() API, but the trace_state in synth_event_trace() and synth_event_trace_array() are on the stack without initialization. This means those APIs will see wrong parameters and wil skip closing process in __synth_event_trace_end() because trace_state->disabled may be !0.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
