Details:

Current code fails to allocate zero length pbuf (e.g. for PBUF_RAW PBUF_POOL),
fix it.

Fixes: eb269e61b5d3 ("First step to clean up pbuf implementation: add
pbuf_alloc_reference() to allocate pbufs referencing external payload; move
member initialization to common function; simplify PBUF_POOL chain
allocator")

My device running PPPoS stop working with current git tree, this fix make it
work.
