Description

The data structure deferred_spaces that had been introduced to fix up ~~MDEV-24626~~ is actually made redundant by the correct logging and recovery of fil_ibd_create() via FILE_CREATE records.

The deferred_spaces.reinit_all() must be merged somehow with recv_spaces. Most of the rest can be removed, including deferred_dblwr().

The test innodb.doublewrite_debug must be redesigned once more so that there will be a log checkpoint between the INIT_PAGE record and the kill and restart. In this way, the test scenario must use the doublewrite buffer instead of relying on recovery via FILE_CREATE and page-level log records.
