Steven Rostedt 1027fcb206 tracing: protect ring_buffer_expanded with trace_types_lock ...

Impact: prevent races with ring_buffer_expanded

This patch places the expanding of the tracing buffer under the
protection of the trace_types_lock mutex. It is highly unlikely
that there would be any contention, but better safe than sorry.
