o Back out workaround for not resetting lucent cards more than once. With
these fixes, it appaers they are no longer necessary.
o Set wi_gone when the card goes awol: typically when we get 0xffff back from
the card. Also, don't interact with a card that's gone, so we fail in
seconds rather than minutes. Also reduce amount of time we wait to .5s
in wi_cmd.
o clear wi_gone on ifconfig down to give some cards a chance after they wedge
(this appears to unwedge one of my prism cards with old firmware). ifconfig
up will fail quickly enough if the card really is out to lunch.
o Add delay in wi_init of 100ms.
o wi_stop(ifp, 0->1) changes so that we clear sc_enabled so that we
exit out of the interrupt routine by just acking the interrupt
