 Log Message:
 Pull up following revision(s) (requested by nakayama in ticket #265):
        sys/netsmb/subr_mchain.c: revision 1.21
 Since "len" has changed to (unsinged) size_t, the while loop
 condition (len > 0) became less able to detect its underflow.
 So check the subtrahend to avoid the underflow.
 Should fix PR kern/44092.
