Another comment is that better to perform CRC check of dhchap_secret and
generation of dhchap_key right where the secret was specified (e.g.,
nvmet_auth_set_host_key() on the target side).

No need to do it every time for every connection and by that increase
authentication latency. As I wrote in the other comment, it might be 128
or more connections established during connecting to a single NVMe-oF
device.
