This commit message is misleading. What you do is hide an output.

zm_dprintf prints into the debug buffer which seems not to be overflow
protected.

diag_printf prints to the console.

Why do you want to hide this message?
Isn't the CRC what the user will want to check?
And if many retries occur doesn't this alert the user that the transfer
may be corrupted?
