netdev_err should use newline termination but mlx5_health_report is used in a trace output function devlink_health_report where no newline should be used. Remove the newlines from a couple formats and add a format string of "%s\n" to the netdev_err call to not directly output the logging string. Also use snprintf to avoid any possible output string overrun.
