fix QUERY_LOG_GAP_LOCK ER_CANT_OPEN_FILE log crashes the server

Summary:
in mysqld.cc `LogErr(ERROR_LEVEL, ER_CANT_OPEN_FILE)` crashes the server because it does not pass parameter for error message format.
This log is not needed because `query_logger.reopen_log_file(QUERY_LOG_GAP_LOCK)` already writes error log on error.

Squash with "Optionally block/log queries relying on Gap Locks [non-RocksDB part]"
