Steven Rostedt (VMware) eb01f5353b tracing: Handle %.*s in trace_check_vprintf() ...

If a trace event uses the %*.s notation, the trace_check_vprintf() will
fail and will warn about a bad processing of strings, because it does not
take into account the length field when processing the star (*) part.
Have it handle this case as well.
