[PATCH v3 08/15] Write 'stop_desc' of trace status to tfile

[Yao Qi <yao@codesourcery.com>]

The field "stop_desc" of "struct trace_status" is parsed (in
parse_trace_status) when the stop reason is tstop_command or
tracepoint_error.  However, the "stop_desc" is only written to tfile
when stop_reason is tracepoint_error.  Here is an inconsistency.

This patch fixes this inconsistency, as a result, the "tstatus" output
on tfile target is the same as its output on live target.

	* tracepoint.c (tfile_write_status): Write 'stop_desc' of trace
	status to tfile if trace is stopped by command 'tstop'.
