Improve the if_vr driver ever so slightly.

The 6105M and 6102 does not have the DWORD alignment problem, so
don't m_defrag() every packet in the transmit path for those.

More stringent usage of tx-descriptor ring and its flags.

Tested on 6102 and 6105M, other chips may also be able to run
without the m_defrag() but I have neither hardware nor docs to
find out.
