nbd: Less allocation during NBD_OPT_LIST

Since we know that the maximum name we are willing to accept
is small enough to stack-allocate, rework the iteration over
NBD_OPT_LIST responses to reuse a stack buffer rather than
allocating every time. Furthermore, we don't even have to
allocate if we know the server's length doesn't match what
we are searching for.
