MDEV-30404: Inconsistent updates of PAGE_MAX_TRX_ID on ROW_FORMAT=COMPRESSED pages

Browse Source 
page_copy_rec_list_start(): Do not update the PAGE_MAX_TRX_ID
on the compressed copy of the page. The modification is supposed
to be logged as part of page_zip_compress() or page_zip_reorganize().
If the page cannot be compressed (due to running out of space),
then page_zip_decompress() must be able to roll back the changes.

This fixes a regression that was introduced in
commit 56f6dab1d0 (MDEV-21174).
