tracing: Do not stop recording comms if the trace file is being read
commit 4fdd595e4f9a1ff6d93ec702eaecae451cfc6591 upstream.
A while ago, when the "trace" file was opened, tracing was stopped, and
code was added to stop recording the comms to saved_cmdlines, for mapping
of the pids to the task name.
Code has been added that only records the comm if a trace event occurred,
and there's no reason to not trace it if the trace file is opened.

Fixes: 7ffbd48d5cab2 ("tracing: Cache comms only after an event occurred")
