fil_iterate(), fil_tablespace_iterate(): Replace os_file_read() with os_file_read_no_error_handling(). os_file_read_func(), os_file_read_no_error_handling_func(): Do not retry partial reads. There used to be an infinite amount of retries. Because InnoDB extends both data and log files upfront, partial reads should be impossible during normal operation.
