Coverity complains that hb might be null when !prev_b0 is true. It may be right, but not likely.
To make the code more explicit when it parses a complete packet, set got_packet = 1 and test
got_packet instead of prev_b0 which is somewhat obscure.
Use vlib_buffer_free_one rather than vlib_buffer_free_no_next in output.c which takes care of
chain buffers.

outbound -- if we have to drop the packet due to no descriptor space is available, drop the
whole packet, not fragments.
inbound -- check and drop error packets

Need to free the buffers starting from ring->consume+1, not ring->consume
Make use of the cool API vlib_buffer_free_from_ring

Under extreme condition, it is possible for input node to have more than 256 packets available
to process. Add a check to the while loop to prevent overrun buffer_indices and nexts.

chain buffers
If we invoke the subject API with 2 buffers, each with 2 chains, the content of
buffers[0] should be head of 1st buffer, and content of buffer[1] should be
head of 2nd buffer.
What the code did was to put
buffers[0] = head of 1st buffer
buffers[1] = next chain of 1st buffer
buffers[2] = head of 2nd buffer
buffers[3] = next chain of 2nd buffer
This is wrong and can cause crash.
The fix is to only increment bi when the entire packet is found which may consist
of multiple fragments.
