perf top: Add missing newline on pr_err call

The perf_event__process_sample function, when not finding a machine
associated with a sample, was calling pr_err without a newline,
garbling the screen on TUI mode due to a problem introduced by a
recent ui_helpline patch.

On --stdio it would just concatenate the messages for each sample with
no machine associated, fix it by adding the newline.
