Pacify users who get all bent out of shape when they see the "xl%d: command

never completed" message. The RX reset takes longer complete than it
used to, a lot longer in fact than xl_wait() is prepared to wait.
When we do the RX reset in xl_reset(), this cases xl_wait() to time out
and whine. We wait a little extra time now after the RX reset, which
should silence the warning.

Thanks to obrien for finally getting me a box with a NIC that
causes this problem for me to tinker with.
