Improve TX path of the VNIC driver

- Avoid memory leak when nicvf_tx_mbuf_locked() fails
- Introduce nicvf_xmit_locked() routine that uses drbr_peek(),
drbr_advance() or drbr_putback() for a specific ifnet.
This gives more clear and efficient design as well as
prevents from dropping mbufs that where not sent due to temporary
lack of descriptors.
- Add missing ETHER_BPF_MTAP() hook
