[Fix] Fix error format of log message

[HAOCHENYE]

Thanks for your contribution and we appreciate it a lot. The following instructions would make your pull request more healthy and more easily get feedback. If you do not understand some items, don't worry, just make the pull request and seek help from maintainers.

Motivation

If the interval of LoggerHook is smaller than the window_size of LogProcessor, time and data_time in log string are not formatted by LogProcessor:

Modification

LogProcessor assumes time, data_time and eta will appear at the same time(Generated by IterTimerHook). However, the previous implementation of IterTimerHook will only record eta after window_size iterations, which causes time, eta and data_time are not caught by LogProcessor. Therefore, time and data_time are formatted as expected,

BC-breaking (Optional)

Does the modification introduce changes that break the backward-compatibility of the downstream repos?
If so, please describe how it breaks the compatibility and how the downstream projects should modify their code to keep compatibility with this PR.

Use cases (Optional)

If this PR introduces a new feature, it is better to list some use cases here, and update the documentation.

Checklist

1. Pre-commit or other linting tools are used to fix the potential lint issues.
2. The modification is covered by complete unit tests. If not, please add more unit test to ensure the correctness.
3. If the modification has potential influence on downstream projects, this PR should be tested with downstream projects, like MMDet or MMCls.
4. The documentation has been modified accordingly, like docstring or example tutorials.
