 Description   

We enabled OP_MSG checksums to catch data corruption on the wire in SERVER-28679.

This work of performing those checksums is extra cost though, and it is redundant when mixed with the hmacs required by tls.

We lose little on the data integrity side and avoid overhead if we only perform check sums on non-tls connections.
