In standby mode, we don't actually report progress of recovery, but up until now, startup_progress_timeout_handler() nevertheless got called every log_startup_progress_interval seconds. That's an unnecessary expense, so avoid it. Report by Thomas Munro. Patch by Bharath Rupireddy, reviewed by Simon Riggs, Thomas Munro, and me. Back-patch to v15, where the problem was introduced.
