In previous patch we added support for integrity checking in the mx full-scan reader. Do the same for the mx reader, which is the one used by all compaction types except for scrub compaction. The mx reader should now support integrity checking for single-partition and multi-partition reads. Single-partition reversed reads were excluded from this patch because they are not used in compaction. Signed-off-by: Nikos Dragazis <nikolaos.dragazis@scylladb.com>
