MDEV-12112/MDEV-12114: Relax strict_innodb, strict_none
Starting with commit 6b69871 the encrypted page checksum is only computed with crc32. Encrypted data pages that were written earlier can contain other checksums, but new ones will only contain crc32. Because of this, it does not make sense to implement strict checks of innodb_checksum_algorithm for other than strict_crc32. fil_space_verify_crypt_checksum(): Treat strict_innodb as innodb and strict_none as none. That is, allow a match from any of the algorithms none, innodb, crc32. (This is how it worked before the second MDEV-12112 fix.) Thanks to Thirunarayanan Balathandayuthapani for pointing this out.
