net: nbuf: Make sure ll_reserve is not holding previous value
While testing SLIP driver, I found out that after some packets, the
ethernet L2 was getting the eth hdr pointer 14 bytes behind the proper
place. That's because at some point the slip driver got a buf which had
been used already, and thus had a ll_reserve value set from previous
usage. That's bad, so let's make sure ll_reserve is 0 when we take a
buffer. (Note that ll_reserve and reserver_head is much different at
this point).
