          How to repeat:

          Create database for LinkBench using page compression and e.g. example_key_management. Start load phase by using trim and atomic writes.

          MDEV-8273: InnoDB: Assertion failure in file fil0pagecompress.cc line 532

          Analysis: Problem was that actual payload size (page size) after compression
          was handled incorrectly on encryption. Additionally, some of the variables
          were not initialized.

          Fixed by encrypting/decrypting only the actual compressed page size.
