Log Message:
Null out sc_rx_mbuf[i] after m_freem to avoid double-free later.

>From Ilja Van Sprundel.

Also null out sc_tx_mbuf[i] after m_freem, out of paranoia.

XXX Not entirely clear to how tx mbufs are freed, but no way to test
this since it's ews4800mips- and hp700-only, so not keen to make any
more elaborate changes...
