Fixed as of the upcoming 5.7.12, 5.8.0 release, and here's the changelog entry:

InnoDB attempted crc32 checksum validation instead of innodb after a
crc32 checksum validation failure, causing repeated crc32 checksum
validation attempts. Checksum validation order is now optimized
dynamically. 

Thanks to Daniel Black for the patch.
