Warner Losh a7db1b744a Fix a race between setting up the interrupt handler and it firing by
setting the data prior to setting up the interrupt. Now we only set
the cookie afterwards, and that (a) cannot be helpd and (b) isn't used
in the ISR.

* In NetBSD, the drivers are responsible for activating each

* FreeBSD, all that's done automatically in the typical lazy
* way we do device resoruce allocation (except we pick the
* cfe up front). This is the biggest depature from the
* inherited NetBSD model, apart from the FreeBSD resource code.
*
* This seems to work well in practice for most cards.
* However, there are two cases that are problematic. If a
* driver wishes to pick and chose which config entry to use,
* then this method falls down. These are usually older
* cards. In addition, there are some cards that have
* multiple hardware units on the cards, but presents only one
* CIS chain. These cards are combination cards, but only one
* of these units can be on at a time.
*
* To overcome this limitation, while preserving the basic
* model, the probe routine can select a cfe and try to
* activate it. If that succeeds, then we'll keep track of
* and let that information persist until we attach the card.
* Probe routines that do this MUST return 0, and cannot
* participate in the bidding process for a device. This
* seems harsh until you realize that if a probe routine knows
* enough to override the cfe we pick, then chances are very
* very good that it is the only driver that could hope to
* cope with the card. Bidding is for generic drivers, and
* while some of them may also match, none of them will do
* configuration override.
