Description

Even with the ~~MDEV-12112~~ fix, Mariabackup seems to fail to verify the pages of page_compressed=1 tables. The reason is that both fil_space_verify_crypt_checksum() and buf_page_is_corrupted() will skip the validation for such pages. We should call fil_page_decompress(), similar to the one that is performed in buf_dblwr_process().
