In dgrp_receive() there is:
desclen = ((plen - 12) > MAX_DESC_LEN) ? MAX_DESC_LEN :
plen - 12;
strncpy(nd->nd_ps_desc, b + 12, desclen);
However, it's possible for plen to be <= 12 here so we'd be passing a
negative number into the strncpy(). Fix this to not make the strncpy
call and report an error if desclen is <= 0
