Initialize 9us slot time as that is what is used mostly
(for non-ERP cases) and also to be in sync with initvals.

Why does it matter, mac80211 tells the driver to reconfigure it anyway.
Also, why use the stupid ATH9K_SLOT_TIME_* enums? I think we should
simply remove those.

I doubt that using long slottime might affect random backoff. so let it
to be in sync with initval till it is altered. am i right?

If you want to get this change in, I don't care. I'm just saying it
doesn't get left at the default long enough for it to matter in any way.

In most of the case, mac80211 set as 9us and also initval uses 9us.
The what is the problem of setting 9us as default. If you want to
remove ATH9K_SLOT_TIME_* enums, ath9k should not set slottime till
it got configured.

I don't see a problem with the change aside from the fact that it should
not make any difference at all, so I don't really see any point to it.
