s/reminded/the remainder of/

In fact, if we generalize this just a bit more, and let the caller
choose whether to use NBD_REP_ERR_INVALID or NBD_REP_ERR_TLS_REQD or
NBD_REP_ERR_UNSUP, then we can merge this functionality directly into
nbd_opt_drop() instead of adding another function.  I guess I'll have to
merge that into the counter-proposal I have in mind (but at this point,
the counter-proposal won't be posted any sooner than 2.11-rc3, in part
because I'm almost on my Thanksgiving vacation).
