MDEV-39707 Assertion `lsn != 0' failed in log_write_up_to

[Thirunarayanan]

Problem:

innodb_make_page_dirty(): Unconditionally calls log_write_up_to() with mtr.commit_lsn() after committing the mini-transaction. When the mtr produced no redo records when the targeted page is full of zeroes.

Solution:

innodb_make_page_dirty(): Skip log_write_up_to() when commit_lsn() is zero.

Code Review

This pull request addresses the issue MDEV-39707 where an assertion lsn != 0 failed. In storage/innobase/handler/ha_innodb.cc, the call to log_write_up_to is now conditionally executed only when mtr.commit_lsn() returns a non-zero LSN. Additionally, a corresponding test case has been added to the InnoDB test suite to verify this behavior. I have no feedback to provide.
