NBD_CMD_DISC is a disconnect request, not a data discard request.

Although this is not 2.10 material in isolation (it is only a
bad trace message), I don't mind including it in a larger pull
request; I'm still planning to fix the issue of a client hanging
on a malicious server in time for -rc3 (whether via Vladimir's
patch or a smaller one that I'm testing locally).
