MDEV-21918 improve page_zip_verify_checksum()
actually, page_zip_verify_checksum() generally allows all-zeroes
checksums because our CRC32 checksum is something like
crc_1 ^ crc_2 ^ crc_3
Also, all zeroes page is considered correct.
As a side effect fix nasty reinterpret_cast<> UB
Also, since c0f47a4a5842 innodb_checksum_algorithm=full_crc32
exists which computes CRC32 in one go (without bitwise arithmetic)
