MYNEWT-83: use a fixed buffer for reception.
The changes for this ticket caused the code to ack a packet at
the link layer even though it was not handed to the host. This
is an error; the link layer should only ack data packets that
were handed to the host.
> Controller should use a fixed buffer for reception as opposed to mbufs

> The current controller code allocates mbufs for reception. During the
> unplugfest it was noted that is was fairly easy to overload the
> host/controller with packets. A probably better way to implement this is to
> have a global receive buffer and we copy out into a mbuf if needed. Note that
> the transmit portion of the controller already uses a global buffer for
> transmission.
