A couple of fixes for tracing:

- Prevent a NULL pointer dereference in the error path of rtla

- Fix an infinite loop bug when reading from the ring buffer when closed.
  If there's a thread trying to read the ring buffer and it gets closed
  by another thread, the one reading will go into an infinite loop
  when the buffer is empty instead of exiting back to user space.
